Summary:

The Moog Moogerfooger MF-107 FreqBox is one of my all-time favorite effects stompboxes. It hasn’t been covered at Best Guitar Effects, so I chose it for my first review contribution. Among my collection of effects pedals, it’s been like a versatile wild haired member of the band.

The Moogerfooger line of stompboxes was introduced in 1998 with the MF-101 Lowpass filter. The MF-107 FreqBox was added to the Moogerfooger line in early 2007. It was the first new stompbox to be produced by Moog after Bob Moog’s death. Other notable Moogerfooger releases include the MF-104M Analog Delay and MF-108M Cluster Flux.

The FreqBox sounds similar to a synthesizer because in its interior is actually an analogue VCO that is modified by the input signal in various ways. But while the FreqBox isn’t exactly a guitar synth pedal, Moog’s deep experience in analog synthesis and sound design are showcased strongly in this unique instrument, making it an original sound design tool with many possible uses that extend well beyond what musicians may expect from a typical guitar pedal.

Features:

The FreqBox contains an analog VCO with a continuously variable waveform which can be modulated by the audio input signal. Modulation of the VCO includes: hard sync, frequency modulation (FM), and modulation of the VCO frequency by an envelope follower. The amplitude of the VCO is controlled by the amplitude of the input signal.

Sound Design

  • Analog VCO
  • Front panel knobs for VCO frequency, Waveform, Drive, Output Level, Envelope Amount, FM Amount, and Mix
  • Sync switch On/Off

Hardware

  • Black brushed metal casing
  • Polished wood side panels
  • Metal bypass switch
  • Led bypass indicator

Ins & Outs

  • Audio in & out
  • CV/Expression Inputs for Frequency, Wave, Envelope Amount, FM Amount, and Mix
  • CV outputs for Envelope, Oscillator

Audio quality

  • All analogue circuitry
  • Classic Mooq designed oscillator and synthesis components
  • The input sound is not a processed version of the input signal, but the sound of the input signal modulating the oscillator.

Build Quality

The brushed black metal casing, knobs, and polished wood paneling of the FreqBox look good and relay serious quality. It takes up more space on a pedalboard, so that could be a consideration. I use the FreqBox in many different setups, so I usually hook it up real time on the floor, rather than keeping it dedicated to a pedal board. Although it’s a larger effects box, I think its size also makes it easier to see and tweak, especially in low light.

Sound & Performance:

Sound Sculpting

To get things started, I set the FreqBox’s Input knob so that the sound is the same level when the pedal is bypassed or activated. The FreqBox has a competent Drive with a nice analog warmth, but the real fun is exploring the harmonic distortion and fuzz overtones shaped by the continuous waveforms, FM amount, VCO Frequency, and Mix knob with the Sync mode switched on. These are not classic distortion sounds, but they provide a jagged glow of rich harmonics to explore and experiment with. Players can find a beautiful unique edge that serves a given vibe and cuts through a mix, especially when used with guitar or bass.

Playability

One of my favorite ways to use the FreqBox is to fatten up a drum machine with a bit of drive and use a CV waveform or sequencer into the Frequency input to create bass lines. In this mode, I would have the Sync switch off and the Mix knob about halfway which allows both the drum machine and FreqBox to sound like separate yet entwined instruments. While the drum machine is going, the FreqBox becomes playable as hands are free to tweak the knobs. Without other effects in the chain, the sounds will cut through and the changes can be harsh and drastic. Adding a filter, delay, and reverb to the chain and slowly tweaking the FreqBox’s knobs can create a vast range of evolving textures and melodic sequences to explore in a single session.

Demo With Drum Machine

Overall-Rating-5.0

The Moog MF-107 FreqBox has a significant range of harmonic sound sculpting flexibility from its oscillator & synthesis features and can be used on just about any electronic instrument sound source. Its CV ins and outs work with expression pedals or other modular gear for deep connectivity in any pedal and/or modular setup. The FreqBox’s creative potential makes it one of the most unique, fun, and versatile effects boxes to own. While it’s not a typical guitar synth pedal, the synth-inspired textures produced from this pedal make the MF-107 quite enticing for guitarists, synthesizer enthusiasts, or any musicians seeking interesting new sounds and textures from their effects pedals. Although the FreqBox is currently out of production, I would definitely recommend prowling for a used one if you’re in the market for an inspiring pedal that will take your music in exciting new directions.

That concludes our Moog Moogerfooger MF-107 FreqBox review. Thanks for reading.
