Once upon a time there was a legendary piece of guitar gear. It was called the Echoplex (EP-3). Many great guitarists from lands distant and near used this epic device to create tones of legend still sought after to this day. These noteworthy guitar giants include, to name but a few, Jimmy Page, Eric Johnson, and Eddie Van Halen. The EP-3 had a distinctive preamp section which such guitarists used for its subtle, yet mythical effect on their tone. Xotic sought to capture the magic of the EP-3 in a tiny little box. In our Xotic EP Booster review, I’ll tell you a tale about what might be the best guitar clean boost pedal you’ll ever own.
Up to +20db discrete FET design clean boost
Internal +3db dip switch for setting the minimum boost level to 0 or +3db gain
Internal Bright Switch for adjusting the EQ from a normal FLAT EQ setting (ON position) to a darker, VINTAGE setting (OFF position)
True Bypass for eliminating any signal interference when switched off
Sound & Performance:
Okay, time to get serious. I have to first start out by saying this is a difficult pedal to talk about. Why, you ask? Well, because it does something. And it does something pretty amazing. But it’s hard to describe exactly what that is.
First off, I plugged my Strat straight into the EP Booster and into a clear clean amp channel. I struck a simple G chord. Then I kicked in the EP Booster with its single knob set around 9 o’clock and strummed again.
It’s almost as if my guitar was dead before and it suddenly came alive. It’s hard not to speak about this pedal in abstract terms. It’s as if the EP Booster reveals a previously hidden dimension to the sound of your guitar.
I originally thought I was hearing a boost of some kind to the low and high frequencies, but after repeated A/B listening to the sound with and without the EP Booster it’s as if simply adds more harmonic depth to the sound.
I’ve realized that it’s hard to accurately explain this pedal in any way. You just have to hear it for yourself. Every tone-obsessed guitarist owes it to their ears to try the EP Booster. It’s like this pedal sprinkles magic all over your tone.
With the +3db switch off and the knob rolled all the way down, the signal matches your bypassed tone with unity gain. With the pedal engaged, the pedal somehow evens out your tone ever so slightly. It’s subtle, yet distinct at the same time. This pedal is full of strange contradictions in the best possible way.
Flipping the Bright Switch to the off position gives your tone a noticeably darker, vintage sound. The EP Booster shaves off just the right amount of high end to wrap your guitar signal in a gentle warmth. My only complaint with this pedal is that the dip switch functions aren’t located on top as tiny flip switches. I can’t decide which mode I like more, bright or vintage, and I’m sure I’d find a frequent application for both if I didn’t have to open the pedal. Although once you find the setting that works for you, you may never have to touch the pedal again.
On clean channels the knob serves to add a considerable amount of boost, great for defining a boosted lead tone. But considering how the mysterious magic of this pedal increases as you turn the knob, you may want to turn it up to a level that suits you and tailor your amp tone and volume level around the EP Booster. It may just become that indispensable to your sound.
The noise floor does rise as you crank the knob, so only a little bit of this pedal’s characteristic boost may be necessary. But no matter how you use it, it’s hard to get a bad sound from the EP Booster.
On high gain amp settings, the volume boost from the EP Booster becomes diminished, but the mojo from the pedal remains ever present. Seriously, you can just leave on and forget about it. Its subtle character enhancement sounds good for any sound.
For the duration of this test I used the Voodoo Labs Pedal Power 2 to supply current to the EP Booster. Like the Xotic SP Compressor and Xotic SL Drive, the EP Booster and also be powered at 9V and 18V. The sound is just as clear and full at the higher voltage, and while the difference is again subtle, there is a slight jolt of additional power and impact from running the EP Booster at 18V. It’s an option worth considering if you have an 18V power supply available.
Okay, let’s wrap this up.
The Xotic EP Booster really is a magical little box. Once you play through this pedal you may never want to play without it again. The EP Booster will add a new dimension to your tone, revealing a harmonic character that seems to upgrade your sound in the best possible way. Warning: only try this pedal if you’re able and willing to make a purchase. This is one you’ll want to take with you. It may not only be the best guitar clean boost pedal you’ll ever use, but the missing link to crafting your perfect tone.
That concludes our Xotic EP Booster Review. Thanks for reading.
