Fairfield Circuitry

A CV/expression-controlled voltage sag device that uses one pedal's power supply to deliberately under-volt another, creating unexpected fuzz tones, chirps, and weird decays in analog circuits.

A versatile CV source that passes audio through unaltered while generating a 0–7V control voltage from the dynamics of your instrument, functioning as an envelope follower, envelope generator, LFO, and slew limiter.

A passive expression preset switch that toggles a 50k potentiometer on or off, most useful for switching between two expression input settings such as two different tremolo speeds or delay times.

The Hors d'Oeuvre? is an active feedback loop pedal that enables bipolar feedback routing of external signal processing devices and mixing of input and effect return signals.

A passive dual CV/expression attenuator with normalled inputs that doubles as a passive mult, letting you tame modular-level signals before feeding them into expression or CV inputs on pedals.

20% More is a slew-limiting distortion pedal built around a resonant slew limiter that acts as a steep distorted low-pass filter, featuring JFET clipping, sub and upper octaves, envelope follower, and low pass gate.

Roger That is an FM modulator/demodulator pedal inspired by radio signal degradation, producing familiar yet unexpected noise, distortion artifacts, and signal decoherence via a simplified FM mod/demod scheme.

The ~900 is a ferocious fuzz pedal featuring two cascading JFET gain stages, offering a very wide range of gain and adding delicious harmonics.

An experimental fuzz/gate pedal born from an oddball circuit that destroys your signal in the most strangely natural way, tweaked and optimized for maximum stench and unpleasance.

The Modèle B is a stripped-down, always-on version of the Barbershop Overdrive in a tiny enclosure, with no bypass switch and two tone options selectable via internal jumper.

The Barbershop Millenium Overdrive is a simple, original design handmade from matched JFETs, delivering versatile overdrive character from nearly clean to rich saturation.

A passive dual TRS-to-TS 1/8" breakout cable adapter that gives modular and semi-modular gear access to TRS CV jacks, and allows hijacking the expression inputs of pedals with a 5V ring reference.

An all-analogue JFET feedback compressor that works equally well on guitars, bass, vocals, synths, and whole mixes, with a simple three-control interface covering threshold pad, compression ratio, and makeup gain.

Meet Maude is an analogue delay pedal that imparts a dark, tape-like quality with a discrete JFET compressor, dynamic output filter, and full CV capabilities for controlling delay time and feedback.

Long Life is a state-variable filter combining tilt and notch/boost equalization around a 2nd-order (-12 dB/octave) core, functioning as a one-band parametric equalizer with CV inputs and expression pedal control.

Shallow Water is a K-Field Modulator that randomly modulates a short bucket brigade delay time to create non-cyclical vibrato, chorus, and flanger-type effects favouring old tape flavours.

An 8-point passive patchbay in a compact pedalboard-friendly form factor, allowing you to rearrange your signal chain on the fly and patch in 1/8" CV and modular sources.

An analogue implementation of a digital reverb algorithm using bucket brigade devices and a Householder-reflection feedback matrix, creating spaces that are both familiar and unusual.

Randy's Revenge is an all-analogue ring modulator featuring a pure sine wave oscillator and voltage-controlled low-pass filter, capable of trem/vibe effects at low frequencies through to bells and synth-like tones at higher settings.
