After reinventing analog chorus, vibrato, and phaser effects with the Warped Vinyl and Wombtone (and newly released Warped Vinyl MKII & Wombtone MKII), Chase Bliss Audio have now tackled the prototypical modulation effect with the Gravitas Analog Tremolo. All the familiar Chase Bliss Audio control flair is here: ModuShape, 6 surface knobs, 3 parameter flip-switches, 1 preset flip-switch, 2 foot-switches, and 16(!) dip-switches mounted to the top side of the pedal. Before we delve into what all this does, it should be obvious that this pedal offers quite a bit more functionality than your old in-amp tremolo. To those of you suffering from knob-o-phobia, a plethora of classic and cutting edge tremolo sounds are available from the Gravitas even if you just stick to using a few of its surface controls. But more on all that in a moment. Here’s a full feature rundown before we dive into our Chase Bliss Audio Gravitas review to see if it’s the best analog tremolo pedal around.


  • All-analog signal path.
  • Ramp control knob can be set to control any of the 5 parameters (Volume, Tone, Rate, Depth, Sway) individually or simultaneously via dip switches on the back of the pedal. Controls the ramp time in which this takes place.
  • Drive (Ramp) control knob controls the input gain of avery clean, beautiful, and transparent boost when no Ramp dip-switches are in use.
  • Volume control knob sets the output level of the effect. This is a little different than the other Chase Bliss Audio pedal volume knobs. It should be pretty much dimed, with the level set with the Drive control. The main purpose of having this knob is so that you can set up a second tremolo (via Ramping), and then adjust the depth of it.
  • Tone control knob is a wide ranging tone shaping tool. When set to noon, the pedal is transparent. Clockwise for a brighter sound and counterclockwise for a smoother, mellow, dark sound. This circuit is also the basis for the harmonic tremolo as that effect is achieved by modulating between high and low pass filters.
  • Rate control knob controls the rate of the tremolo effect – can get super fast. Can be overridden by the tap tempo switch.
  • 1 – 2 – 4 (3 – 6 – 8/S – B – H) toggle switch sets the tap division for tap tempo. A dip switch on the back accesses the “3 – 6 – 8” divisions. Another dip-switch allows this switch to select between Standard, Both, and Harmonic tremolo modes.


  • Depth control knob sets the depth of the tremolo effect. Crank if for modulation going all the way to silence.
  • Sway control knob sets the center point of the modulation. Set it counterclockwise to make the wave ramp up quickly and down gradually. Set it clockwise to make the wave ramp up gradually and down quickly. Set it at noon for a perfectly symmetrical wave.
  • Left Wave Shape toggle switch sets the first half of the wave modulation. Left for sine, middle for triangle, right for square.
  • Right Wave Shape toggle switch sets the second half of the wave modulation. Left for square, middle for triangle, right for sine.
  • Bypass foot-switch activates or bypasses the effect via true relay bypass. Can by changed to a momentary bypass via a dip switch in the back of the pedal.
  • Tap Tempo foot-switch sets the tap tempo and always honors the last two stomps.
  • Preset toggle switch recalls presets. Middle position reflects current knob positions, right position recalls right preset, and left position recalls left preset.
  • Exp/CV input jack allows expression pedal or CV control of parameters selected via dip switches on back of pedal. When no parameters are set to Ramp, it manually controls the Waveform.
  • Tap/MIDI input jack can be used for tap input or output with a regular ¼” instrument cable. It may also be used to interface with the pedal via an Empress Effects Midibox.
  • Powered by 9-volt battery or 9VDC power adapter. Can also be run at 18-volts for more headroom and output.

Chase-Bliss-Audio-Gravitas-Review-Best-Analog-Tremolo-Pedal-03Dip Switches:

  • Volume, Tone, Rate, Depth, and Sway dip switches on the left side simply turn that parameter on or off for ramping or expression pedal capability.
  • Volume, Tone, Rate, Depth, and Sway dip switches on the right side control whether the parameters rise or fall in ramp mode. This also affects the direction of movement with an expression pedal.
  • Bounce dip switch makes parameters go back and forth (i.e. modulate) or ramp and hold.
  • Mode dip switch allows left flip-switch to select tap divisions or tremolo mode.
  • MoToByp dip switch activates momentary bypass, activating pedal only when Bypass foot-switch is pressed in.
  • Tap Control dip switch allows tap tempo to modulate Ramp rate (r) or tremolo Rate (p). Bounce needs to be on to modulate Ramp speed.
  • Tap Division dip switch selects from “1, 2, 4” tap divisions (1) or “3, 6, 8” tap divisions (3).
  • Sweep dip switch selects where Ramp sweeps. In “t” (top) the ramping (or expression control) will occur between the current Ramp knob position and the max position (fully clockwise). In “b” (bottom) the range is set between the current knob position and the minimum position (fully counterclockwise).

Sound & Performance:

I’m going to cover the functionality of this pedal gradually. We’ll start with the traditional sounds it offers and the simplest aspects of its controls and slowly delve into the more complex stuff.

Classic Tremolo Reinvented

This is where the Gravitas excels, or should I say, shows its gravitas. Throbbing volume modulation oozes out of this pedal with classic and new sounds being very easy to dial in. There are 3 tremolo modes available: Standard, Harmonic, & Both. Standard mode is the classic style tremolo effect, and thanks to ModuShape (see below), you can achieve a smooth volume pulse or unconventionally offset and jagged warbles. Harmonic mode allows the LFO to modulate the Tone of your signal for a subtle and unique tremolo-style filtering effect.

The “Both” setting is where things get really interesting. The Gravitas’ combination of Standard tremolo mode with the unique Harmonic mode is a most welcome twist on tremolo design as it provides a dynamic tone adjustment as the volume swells for a blooming effect in the upper frequencies. You can use the Tone knob to choose just how bright the tremolo gets at its peak. The effect is subtle yet beautiful; while I thought it might be an interesting novelty, it quickly became my preferred mode.


This has become a staple of the Chase Bliss Audio pedals released so far (see Warped Vinyl MKII & Wombtone MKII) and is a brilliant and simple way to set the LFO waveform for modulation effects. For a quick “classic” tremolo sound, simply set the Depth and Sway to noon and flip the 2 ModuShape toggle-switches to Sine (facing away from each other). From there you can adjust the Depth to taste. Pulling the flip-switches to their middle positions brings in a slightly sharper Triangle waveform, a great classic trem variation when used with lower Depth settings. Setting the switches inward to Square produces a hard trem effect that gets pretty choppy when maxing out the Depth. While it isn’t the most machine-like, gated chop I’ve heard in a tremolo (most likely due to the particular nature of this pedal’s analog design), it’s still more than adequate for producing those jagged stuttering trem effects, especially when used in a mix with other instrumentation. Also, using the various waveform halves in combination and exploring the Sway knob settings (which lop-sides the waveform) will yield some inspiring, unorthodox sounds.

Drive/Volume & 18-Volt Operation

An interesting thing about the Gravitas is its Drive/Volume knob arrangement. The Drive knob controls a clean boost gain stage located before your signal is fed into the tremolo effect. The overall output is set post-tremolo with the Volume knob. Chase Bliss Audio advises in the Gravitas manual to dime the Volume knob and use the Drive for setting your output level. As stated in the manual, “the main purpose of having this [Volume] knob is so that you can set up a second tremolo, and then adjust the depth of it.” You can use the Ramp function to modulate the Volume, thus achieving 2 separate tremolos. (You could also run 2 Gravitas pedals in series for synchronized, rhythmic tremolo sounds via MIDI Clock. I tried it. Fun stuff.)

In the Gravitas manual Chase Bliss Audio also mentions under the “Drive (Ramp)” section how using the pedal with 18v can result in “more headroom and output”. Since it specifically mentioned this in relation to the Drive knob, I spent some time comparing running the pedal on 9-volts (via battery) and 18-volts (via power supply). With the Drive knob rolled all the way down, the difference is negligible. The voltage difference doesn’t really affect how the Volume knob performs. But as you increase the Drive it becomes apparent that the different voltage does have more of an impact on the overall output and high-end presence of your sound. This leads me to prefer using the Gravitas at 18-volts with the Drive knob at higher settings. I’ll then use the Volume knob for setting the output (contrary to the manual’s recommendation) as the benefits of 18-volts are most noticeable to my ears with higher Drive settings. At this point you could also roll the Depth all the way down and use the Gravitas as a hi-fi, 18-volt clean boost with complementary Tone control.

It’s important to understand that the Drive essentially pushes a “hotter” signal into the tremolo when used at high levels. It doesn’t quite get dirty on it’s own, but if you want your overall sound to be as clean as possible, try dialing it down a bit. Also, while I personally prefer the 18-volt sound of the pedal, the Gravitas still sounds great at 9-volts. 18-volts will be mainly worth considering if you just really want to extra headroom or if you really need that little extra volume output (which is useful if you use extreme Rate settings as they tend to reduce the overall output level, typical of all tremolo pedals).


This is where things get even more interesting. Another Chase Bliss Audio hallmark, the Ramping functionality lets you modulate parameters by setting them to “ramp” via dip-switches for each of the 5 parameters (not including Drive). With the Warped Vinyl MKII & Wombtone MKII, I find myself getting pretty wacky with the myriad ramping possibilities, but with the Gravitas I find more restrained ramping to be most effective. For example, simply modulating the Volume by setting it to Ramp and “Bounce” up and down produces a double-tremolo effect. (The left preset showcases this.) I also like to set the Tone control to a long “Ramp and hold” with Both mode (Standard & Harmonic) so that it gradually increases to the brighter sound set via the Tone knob. You could also have it Bounce back and forth for a little tonal variation behind your tremolo. And it’s fun to get a little funky with the Rate & Depth to go from a dry and slow to wet and fast tremolo.

MIDI Implementation

The Gravitas lets you save 2 flip-switch selectable presets to access from the surface. If you want to go deeper, you can save and recall 122 additional presets via MIDI. This is a godsend if you want to use this pedal in a MIDI rig and select your presets via MIDI. You can also control the knob parameters via CC messages. There’s even a CC for changing the Tap Division. I was able to program some Tap Division automation in Ableton Live for some pseudo-Goatkeeper style pattern tremolo effects. Also, as I mentioned previously when running 2 Gravitas pedals in series, MIDI Clock can help keep the pedals in sync. I used the Molten Voltage Tempode to keep both pedals in time. You could theoretically create and recall presets on 2 pedals to reproduce whatever crazy tremolo patterns you come up with.

Chase-Bliss-Audio-Gravitas-Review-Best-Analog-Tremolo-Pedal-04A few notes about the size of this pedal and its practicality in use. It never ceases to amaze me how much Chase Bliss Audio can stuff into a reasonably standard sized pedal enclosure. (Notice how even the foot-switches are mounted at an angle inside to allow just a little more room for the PCB.) Looking from the the outside, it may appear concerning to have the Tap Tempo foot-switch so close to the Bypass foot-switch, but in use this isn’t too much of an issue. You’ll have to use the right edge of your shoe to tap in the tremolo to the beat, but then a hearty stomp on either just the right foot-switch or the general foot-switch area will activate it. If you’re using the Rate knob to set the tempo, you don’t need to worry about accidentally pressing the Tap foot-switch when activating the pedal as a single press won’t change the tempo. Still, for maximum utility, the Gravitas performs brilliantly with MIDI and is how I’d most recommend using this pedal in your guitar rig.

Chase Bliss Audio have pretty much covered the analog modulation essentials as this point with the Gravitas rounding out their pedal lineup. While my personal tastes usually lean towards super aggressive, choppy tremolo effects, for classic analog tremolo tones (in mono) this pedal is tough to beat. As I spent more time with it, it really won me over, mainly thanks to the innovative Harmonic mode which gives this pedal a unique sonic edge over other basic tremolo guitar pedals. And the Gravitas is an especially great compliment to the Warped Vinyl MKII for capturing an old timey, vintage vibe. Speaking of vibes, a Uni-Vibe style of pedal would be perhaps the only other modulation pedal I can think of that I’d like to see next from Chase Bliss Audio, but it’ll really be interesting when this company finally releases a delay pedal or ventures into the realm of fuzz or distortion.

The Gravitas is another winner from Chase Bliss Audio. Let’s see the final result.



The Chase Bliss Audio Gravitas is one of the most beautiful sounding analog tremolo pedals I’ve had the pleasure of playing. The pedal’s combination of Standard tremolo and Harmonic mode produce some of the most inspiring and unique tremolo sounds around. As a classic tremolo the Gravitas excels, but the extra subtleties really make this pedal something special. And if you like having a ton of presets, MIDI control, and perfectly synced tremolo via tap tempo or MIDI Clock with your classic tremolo sounds, the Gravitas should be the next pedal on your must-buy list. In terms of a mono-only analog tremolo, this is the best one there is.

That concludes our Chase Bliss Audio Gravitas review. Thanks for reading.

  1. The most innovative pedals I’ve seen in a while! Great sounds and versatility from a really cool looking company!
    I don’t want them, I NEED THEM!
    Keep up the great work.
    South Africa

  2. This is capable of the fast “chop” tremolo I like, something I can’t get in many others. Plus the midi allows pattern sequences to be done as well. Killer!

  3. The amount of features packed into this pedal is ridiculous, and they arent just useless features, all have really useful applications and are features i would always use, really great design :)

  4. I’ve never heard or seen a tremolo pedal like this one, the ramping makes it seem extremely versatile compared to a tradition trem pedal. Excited to try it out!

  5. Love the sounds I’ve heard from this thing and all the controls available (although I personally wouldn’t use all of them). I like tap on a tremolo, and would especially use it in swells. You can dial in some sweet tones with a trem/delay/VP combo!

  6. I’ve just started to build a small pedal board, my first, and I’ve only got three currently, a H.O.F, Harvester Overdrive, and a Polytune. I’ve been looking into tremelo pedals for a while and found this to be the one i’d like to own, when I can eventually get $500 NZD, i’m also going to pull the i’m a poor student card here. #zerodollars

    But in all honesty, I’ve listened to a few videos on youtube and I’ve seen none compare to the Gravitas, i’m thoroughly impressed with the quality for sounds and diversity this pedal can do (from what i’ve seen).
    It’s the dream pedal i’d love to have to see what sounds I can make and shape in my own music.
    On my board I don’t want to waste time getting a simple pedal, I’m only interested in pedals I can get a diverse range from, this is definitely one of those i’d love to buy eventually.

  7. This pedal is amazing. I can’t believe the possibilities that are available with the use of the dipswitches. Would be great to use this from small subtle tremolo sounds to large rhythmic effects. Voice of its own, Love it!

  8. This is the pedal I’m buying after I get a Warped Vinyl. I love tremolos and this one sounds incredible. I want to have a step sequencer controlling all three Chase Bliss pedals

  9. This Gravitas tremolo is the only tremolo pedal I’ve ever wanted to own. I’ve been looking for one that sounds this good for 2 years now. I’ve never owned a trem pedal before because none have sounded this amazing before! No matter what setting I’ve seen dialed in on these it’s always mind blowing. You guys are the best. I will use this pedal to its full capabilities every single night when I’m leading guitar in worship. Whether I win this or not. One day I will own all Chase Bliss Audio pedals and never let them leave my board. Thanks for making such awesome gear guys. You rock!

  10. Wow Chase Bliss stuff is in a whole different stratosphere, and it’s sounds bring me to a whole new planet. Really can’t get any better than this for a Trem, absolutely gorgeous sounds that I would love to add to my board. This thing can make some lucious sounding ambient noises that keep me glued to my guitar for hours. Love what I’m seeing from these guys.

  11. This is easily the most impressive tremolo I’ve ever seen!!
    I’d love to see what it could do with violins & pianos run thru it…but my guitars (Ac. & Elec.) would get first crack.
    If I got brave I’d run a mic thru it too. That would be fun.

  12. I have this love hate relationship with tremolo, I even sold my empress tremolo because I didn’t care for it much. However upon hearing that CBA made a tremolo I knew I had to have it. I think I fell in love with tremolo again.

  13. The Chase Bliss gear is on another level! You never knew that you needed an analog teen so badly, until you hear this one! Absolutely killer!

  14. I am excited to try this pedal out. The tweak-ability and versatility of this beast is amazing. Tremolo is one of my favorite effects and Joel does it right.

  15. To be able to Frankenstein the front and back of your own amp envelope is unbelievable, and that’s just a small part of what I would ask of this trem when pushing it to its limits.

  16. This here is a pedal needed on every board to give that extra depth. Like a magical unicorn. You need it even if if you don’t think you do. It’s needed on my board.

  17. Not that this pedal wasn’t already phenomenal but Knobs made this thing look so good. The Gravitas has made me a believer in ~space tremolo~.

  18. Every time I see a Chase Bliss pedal I want it. I want a pedalboard of just Chase Bliss. When you hear these pedals you’re hearing the art of crafting and engineering effects taken to the next level.

  19. I tried to build a tremolo pedal once. It’s in a box somewhere. In like 400 pieces. Mine had 2 knobs. This one has like 14. I’m not sure if that number is accurate. I’d like to see more of this pedal. Preferably in my room alone. In the dark. With Barry White playing in the background.

  20. Using harmonic tremolo + sine ^ and square v = coolest filter’y, phase’y pseudo-reverse delay effect ever. Can’t wait to add to my board.

  21. Chase Bliss is genius. They’ve redefined what’s possible with a guitar. The gravitas is the texture I’ve always needed but didn’t know that I did until its existence

  22. Tried one of these in a small boutique pedal store where I live. I absolutely love the sound of this pedal. Perfect for a shoegaze band. I would love to own one of these and include it on my bands next recording. Definitely a shoegaze bands’ go to pedal company.

  23. I’ve been looking into tremolo pedals for a while now and I’ve been on the fence. I’m not on the fence anymore! This one has a ton of options and would be exactly what I was looking for in terms of control and ability. Mmmmmm yessir!

  24. Pro level. I like the all-analog signal processing with the flexibility of controls. No shuffling through presets. As adjustable as plug-and-play gets!

  25. Right now, I’ve got a tremolo pedal that is a bit weak. The volume drops and I’ve got two controls, depth and rate. The Gravitas sounds great! The amount of options this pedal offers is fantastic. Talk about a pro level pedal. The Gravitas is it!

  26. Surely the most versatile Tremolo on the market; the harmonic mode is what really sets it off for me. I’d imagine getting more subtle effects running this after a two-way crossover just slicing the bottom end.

    Safe to say my Seymour Duncan Tap Tremolo is obsolete anyway.

  27. So far i’ve had 3 tremolo pedals: the tremolo on the Boss ME-50, the Electro Harmonix wigglers and a cheap and cheerful Hofner affair. All of them have been a disappointment so far. None of them even come close to sounding as magnificent as the Gravitas. It affects my senses in much the same way as i’d expect a lump hammer wrapped in kittens would. Hard hitting but at the same time unutterably adorable!

  28. I love the obsessive level of detail in the functionality. It’s like they pulled the souls out of 100 regular trems and made the be-all and end-all of trems. It’s like he knows that the end is nigh, and that he must leave behind the best possible tremolo for future alien civilizations to find in the rubble of our world, long after we are gone.

    I didn’t really feel the need to have a tremolo at all, but after watching this video, I am fully convinced that I need two! How did that happen?

  29. when this guy releases a delay, I promise I will sell all of my delay pedals cause they won’t stand a chance next to that marvel. Until then, I could play this trem really smoothly

  30. I second the desire to see a delay pedal, though I think a flanger is coming next. This seems like it would be a lot of fun with an asymmetric waveform into a delay.

  31. Hi, is this Chase Bliss? um, yeah I was wondering if you could make a tremolo pedal that does literally everything? you can? ok great. thanks.

  33. I just got the Wombtone MKII Acid Etched version and it is unbelievable. This pedal is next on my list and I would love to see what Joel could do with a delay pedal. Unreal mind and creativity!

  34. i feel this guys pain. those look like some painful builds! but hes clearly doing some epic stuff here. this pedal would keep me busy for a year trying to figure it all out. i dont have anything with this many features. my head has less controls! id be thrilled for anyone of his works, but this one is what i gravitated towards. i hope the best for this guy. these are some serious works of art

  35. other makers are getting skunked! it’s clear that chase bliss is leaps and bounds ahead of what had been considered feasible in such a small box.

    makes me really curious for what years down the line is going to look like with him!

  36. This tremolo sounds amazing. Would still be nice if a tremolo did triplets. I wonder what the electronics behind it is that they always subdivide by halves.

  37. I have been saerching for a Tremolo pedal which is a) versatile and b) killer sounding. And I think the Chase Bliss is the first to really cover my needs. How awesome it would be to win this Beauty!! As always you guys did a great review :)

  38. I honestly don’t like entering free giveaways because it’s almost always a waste of time but when I do, I really want the particular item being given as a prize. That being said…I really like the Gravitas and it’s worth more than a follow, sign up and a comment. Here’s hoping!

  39. I love everything chase bliss has made, he’s truly a genius and a gem in the pedal business. I love tremolo and the gravitas takes my tremolo love to new heights.

  40. This is the end all be all of trem pedals. Such awesomeness!!! This seriously is one of the most impressive Tremelo pedals I’ve ever heard!

  41. That’s a lot of tremolo in a little box. Chase Bliss keeps dropping head turning pedals. The kind of builder whose stuff you want to keep getting – all of it!

  42. What I love about all the Chase Bliss products is the ability to go from a normal setting to an out-of-your-mind whacky bones setting… And There is a place for that. Most of the time normal is what people need. For me, I need to leave Earth and grab a sound that no one is doing. It helps me with my process, going outside the box like that. Tremolo is an un-avoidable effect in music. Classic to contemporary. I don’t have a tremolo pedal on my live board because I can’t seem find my personal sweet spot with my bands set list of songs. Watching the demo videos of the Gravitas I already know where I want to flick the dip switches to add life and flavor to numerous amount of lead riffs. Even the clean rhythms, there is so much freedom to create something new and original, and that’s what I live for. Getting the gravitas into a live setting is one thing but being able to take it into the studio would be a dream. Best of luck to everyone and cheers!

  43. I absolutely love the sounds this pedal is capable of. Would love it to play some old 50’s hits and add some spice to my own tunes. Would love to see Chase Bliss make a Tubescreamer clone with a built in clean boost.

  44. I just spent a fun 30 minutes at my local guitar store trying out the Gravitas with a Tele through a Marshall combo. What a delight – This box does so many things and does them all beautifully – from your standard trem to brownface vibrato-ish stuff to a whole world of wacky things – limited only by your imagination. The build quality is superb and the sound is oh so sweet. Its not a cheap pedal but for fans of tremolo pedals, this is as good as it gets. It is on my serious wants list now.

  45. Looooooove love love Chase Bliss Audio, i got the Wombetone and is an amazing little in size but big in sound pedal. And reading your review on the Gravitas makes me want to get one so bad!!!!!

  46. This Tremolo Looks and Sounds Amazing !!!!!!!!! i hope i get a chance to win this in your giveaway !!!! right now im using a Visual Sound Chopper Tremolo that a friend let me borrow for some original song recordings and its ok just not a stereo pedal ,, Thanks Guys at ” ” KEEP ON ROCKING and ROLLING ((((( hope im entered into this giveaway )))))

  47. To be frank I wouldn’t know what to do with phaser and vibrato. It’s not my cup of tea. Everything I need is somebody to love and this tremolo :)

  48. Great quality with an outside-the-box frame-of-mind makes for a very musically inspiring pedal!. As a producer/keyboardist my only wish would be stereo operation, or at least stereo outs. What’s next. A fuzz/filter? A seq/reverse/verb?

  49. Never had the need for more than just a very basic termolo pedal, but this could obviously warp into new nontraditional sounds that could bring tons of inspiration!

  50. Without a doubt, this is the best, most versitile analog tremolo on the market. It’s brilliant how he uses digital modeling to form the tremolo however you please while preserving the analog signal. Tap tempo is always a necessity on any rhythm based effect, especially delay and tremolo, being able to MIDI sync it just opens up the possibilities. This pedal is so much more than just a tremolo, it’s virtually another instrument. I could get lost for weeks with this pedal.

  51. Well written review! I love the sound of this pedal, especially when using two of them! I also found it very interesting that you’ve opened it up to look at the insides, I hope you didn’t break it! :)

  52. Great review once again. I really wish that this pedal was in stereo or had the option to be in stereo. It sounds great. When it came out, I was drooling over this. I hope they come out with flanger or delay next. A time based pedal would also be awesome, where you can have delay and Echo and morph between the two.

  54. you have got to love trem. just a little will pulse and swirl making you drift. fatten the flavours and tone of your tone. love it love it love it.

  55. Hi,

    here is my comment. The pedal sounds very promising but I can’t say anything about it as I don’t own it yet. …So please let me win one and I’ll write a full review!! ; ) Thanks!!!

  56. I would absolutely love to get my hands on this pedal, or any Chase Bliss box, for that matter. In all honesty, I am intimidated by the learning curve and virtually limitless potential surrounding these pedals. Though it’s not on par with the Warped Vinyl, I do have a decent optical chorus I’m happy with, and I’m not the biggest phazor phan in the world, so Gravitas is where it’s at for me. All the youtubes I’ve watched on this pedal leave me with my mouth agape.

  57. This pedal sounds freaking good. I would love to use it with a MIDI controller and make tons of ramping, momentary, choppy, pattern-like presets. Tremolo is easily one of my favorite effects, and Chase Bliss Audio is changing the pedal game.

  58. This thing is sick.

    Chase Bliss – please do a delay…it blows my mind to think of what you guys would do and the control I would have.

  59. Great sounding pedal. Like the variety of types of Tremolo. Tremolo is one of the go to fx for me always on my board.

  60. this guy must be a ninja! ive never seen so much packed intp a 125b! (assuming its 125b?) iid love to figure that thing out! the rubix cube of sound

  61. This review of Gravitas just make me have second thoughts about what should be my next “Chess Bliss Audio” pedal…

  62. Wile mixing,recording, producing tracks and bands y do re amping for the most part
    i will love to try this pedal on diverse material and crate some exiting tremolo fx
    the possibilities could be endless! vocals keyboards strings cellos you name it i will try it

  63. Just one word. Amazing… What are the features that it does not have. I think I’ll get tired if I start to write them. I just wish that I could have one like that in giveaway cuz they don’t sell it in my country. it’ll be amazing. I just love it.

  64. what an ethereal and gorgeous-sounding machine. was almost sold on the EHX Super Pulsar but decided to watch a video of this guy. the sway and harmonic trem sounds are incredible and otherworldly, and it’s fairly clear to me now that i MUST have one of these (would pair nicely with my Warped Vinyl MK I, i’m sure).

  65. What an incredible pedal! Tested one last week and was amazed by the quality, was never really into tremolo pedals, but the Audio Gravitas just blew my mind! I definitely recommend to anyone that’s looking for a top-notch tremolo pedal

  66. Wow, there are so many possibilities here. I have to say that some years ago I would never go for a tremolo pedal, but nowadays I know how freaking awesome those things can be! Need one of those in my pedal set.

  67. I would probably be pretty lost in the beginning sitting there tweaking all those knobs and flipping all those switches but after a while I’m sure I would find very cool sounds. I play bass but I know that a pedal of this quality would handle the lower frequencies really well.

  68. Tremolo pedals are an often overlooked but really versatile thing to have in your sound. I’d love one of these.

  69. Very very cool pedal. I’ve never been super interested in tremolos but the amount of things this pedal can do makes me want to sit and play with it for a few hours. As always the analog signal path controlled by digital is truly incredible. Great website and great review, keep it up.

  70. Sweet tremolo pedal. Definitely gets the job done. I loved the choppy, abrupt tone you got paired with that fuzz pedal. I can also appreciate how the pedal has multiple power options, be it 9 volts or 18 volts, if a player doesn’t have access to a 18v power supply.

    By the way, have you checked out the mini crybaby wah yet? I’ve heard good things about it, but I’ve always been a little skeptical of those mini pedals. Would love to hear your thoughts.

  71. This tremolo looks great! It has so many options for sound and I’m sure the analog aspect sounds really good. Would love to try this pedal and get away from my shitty Boss tremolo

  72. I’ve only tried the tremolo effect on many multi effects because buying a standalone could be expensive. I’m doing a project with a friend and we’re aiming for the silverlake sound. This should be perfect for experimenting. To win it would be sweet because nothing comes out of my pocket.

  73. I tried this thing in a store and I was amazed.
    I don’t usually use trem but I’m sure that this effect would be this all over my songs if I had this amazing pedal. Why? Because it’s not just a tremolo, it’s the Gravitas by Chase Bliss Audio!

  74. I don’t usually use trem but I’m sure that this effect would be this all over my songs if I had this amazing pedal. Why? Because it’s not just a tremolo, it’s the Gravitas by Chase Bliss Audio!

  75. I’m usually not a big fan of tremolo effects, but this one did give me some ideas for how I could make it work. I wasn’t as impressed with this pedal as I was with the others made by Chase Bliss, but it’s still a great sounding pedal nonetheless.

  76. This sounds sweet! Amazing how Chasebliss has made a relatively simple effect like tremolo so expansive and unique. Love this one!

  77. Sweet Lord!! What a sound, the feeling of the tone… what i could do with it? create a music festival with my neighbors every night in my apartment… all night long!!! The next big thing that Chase Bliss Audio can do? Suprise me!!!

  78. Wow couldn’t think they could top the wombtone but this is close.
    Definitely suggestion for next pedal for Joel would be a delay or reverb. Even though market is flooded his take on things with customization might be pretty cool to see how modulation could work in with delay or reverb.
    Also wouldn’t mind to see stereo out on some pedals as option or upgrade or something.

  79. I’d love to try out some bi-amping using a tape echo set to put the modulated pulse through a different signal path.

    I love the thought of being able to automatically do clean note/distored note/clean note/etc or whatever (although there is probably something out there that can already do this and I’m just to lazy to research it!)

  80. I was looking to replace my old PN-2 and this would definitely be a top contender.
    Sadly, it’s out of my price range…
    Totally worth it if you do have the cash, though.

  81. What an amazing pedal! Having watched the ‘Knobs’ review of this pedal I was sold from the first few seconds of the review. Good to see that BGE features it in all its glory. I’m semi-finalizing (since truly finalizing is probably never going to happen) my pedal board this summer and the Gravitas is the most beautiful trem I have seen on the market. Winning this would extasize me to infinity.

    Cheers from holland

  82. That pedal is just too cool man! Joel really is a genius, he fits so much into such a small enclosure, remarkable. Versatility at it’s very finest. Excellente revue des Gravitas par Chase Bliss Audio!!

  83. This pedal is perfect!!! If i would have to choose one of the Chase Bliss pedals…this would be it!!! So much options, perfect sound, presets… I want it!!!

    By the way, nice double-pedal review!

  84. Besides Phase, Tremolo is probably the effect I use most (other than some type of overdrive). Would love to try this pedal out.

  85. Without a doubt the most comprehensive tremolo pedal I’ve seen. Very nice round sound and many variations on the amplitude. In short-would love to have one!

  86. My Strymon Flint has helped me fall in love with tremolo, and this is the first pedal I’d consider switching away for. Thanks for the in-depth review and love note to an overlooked pedal category!

  87. Another amazing pedal by Chase Bliss. The pedal is fully loaded with features. Too many knobs will get any guitarist excited!!!

  88. I just can’t get over how many features are packed into the Chase bliss audio’s pedals, If I won I’d just show people what Chase Bliss can make, it’s seriously mind blowing.

  89. Chase Bliss Audio really packs a punch with this pedal (as with all of their pedals) – would love to win this one. So many options. Would use this for any song that features tremolo like “Crush with Eyeliner” by REM, “Born on the Bayou” by CCR and “Bones” by Radiohead just to name a few. Happy anniversary Best Guitar Effects!

  90. So, its hard to tell from the video demo for this pedal just how slow, dark, and moody this trem pedal can get … but with the features Chase Bliss always packs in there is little chance of any real disappointment. I don’t know what they will tackle next but I look forward to it, though my wallet fears it. (Is there a reverb/echo in the future?)

  92. I really like how the Gravitas can do any tremolo sound anyone could ever want and do it all well. This is definitely the most versatile analog tremolo that I’ve seen.

  93. I really like how the Gravitas can do any tremolo sound anyone could ever want and do it all well. This is definitely the most versatile analog tremolo that I’ve seen.

  94. This is yet another amazing sounding pedal. I’m going to need to get a higher paying job to support my effects addiction.

  95. Finally, a pedal maker is tapping the full potential of tremolo . More user friendly than the zvex sonar (even though both pedals were designed by Joel.) A must have for anyone passionate about tremolo!

  96. A lot of my guitarist friends don’t get this but tremolo is by far my favorite effect and this one sounds beautiful. With all the control on this I would spend a month just noodling around with it. Pretty sure I was born about 30 years too late.

  97. I recently started working with pedals and leaving multi effects behind. I’d love to get this one into my collection!

  98. It is very interesting that one pedal has so much options. This would allow me to explore every aspect of the tremolo effect to incorporate into my sonic landscapes!

  99. That combination of standard and harmonic trem is absolutely gorgeous, yet so incredibly versatile. Fingers crossed!

  100. What can I say? Been waiting for your demo & review for this pedal (trem happens to be one of my favorite kind of modulation) and Chase Bliss left me wordless again with this superb trem!

    I’m crossing my fingers here to be one of the lucky winners!

    Thanks for the demo & great review!

  101. I’ve never owned a dedicated tremolo pedal before, but I’d love to have this one! Wow, it can sound like a traditional tremolo, or something entirely different. This is my kind of pedal – countless hours of heady fun!

  102. Having a tremgasm over here! When I can dial it right, trem is my favorite effect. I would never have a problem with this one.

  103. The Chase has rendered Sonic Bliss and a wild spectrum of Creative possibilities with this one of a kind alchemical machine!
    The beauty of its looks, the charm of its sounds, the haunting desire to have one to play with…
    Gratitude Joel, even if i don’t get one in the meantime the world is a better place with chase bliss (bio)machines – because they do seem to have a life of their own!

    I would love to have this in my vocal pedal board! Running a condenser mic through a radial engineering voco-loco, and a chain of chase bliss gravitas and warped vinyl mkII sounding in a AER compact60! Sonic dream time in unheard soundscapes!

  104. This and all other demos make it sound totally awesome – much love, best tremolo i have heard in a veeeerry long time

  105. How can a “simple” stombox be this versatile?? Can you please tell it to me? :)
    Anyway, I loved the way you used the 2 together! And loved all the 3 Chase Bliss reviews! Thank you for doing this!

  106. Yet another beautiful sound from Chase Bliss,with their usual astounding range of variable modulations and tweaks.Tremolo is so personal players,but this would suit anyone in any style.

  107. Another amazingly lovely pedal from this brand.The range of modulation and variation is,as always,astounding for such a small box of delights.

  108. Very cool, I’ve tested basic tremolo effects, and find them useful for a few applications, but this seems to be so much more than just a regular tremolo?

    Very nice review!

  109. great review as always. i really like what i hear. Chase Bliss is wow! I don’t know if i would have two gravitas, but i would definately connect it with a Warped Vinyl!!!!!

    • Wondering how much overlap this pedal has with the sorts of tremolo sounds achievable through the Wombtone. A lot? Great sound, though! Do want.
