Blended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement.

The Electro-Harmonix Percolator is an analog harmonic saturator, overdrive, and fuzz pedal that reimagines the rare 1970s Interfax Harmonic Percolator circuit, a cult favorite made famous by Steve Albini use on stage and in the studio. It centers on Harmonics and Balance controls for gain and output level, plus a Bias knob that shifts the circuit from smooth transistor-like drive to pseudo-octave and gated Velcro-style fuzz, and a Fuzz/Drive switch that toggles between standard clipping and a lifted-diode mode for a rawer, more organic character. Built on asymmetrical, even-order harmonic clipping, it produces tones ranging from chewy, crunchy overdrive to ripping, unstable fuzz textures rather than a single smooth gain stage. It suits alternative, noise rock, and experimental players wanting an unconventional, harmonically rich drive pedal distinct from typical Tube Screamer or Big Muff voicings, at an affordable price point.
The Fairfield Circuitry ~900 Fuzz is a raw, aggressive transistor fuzz pedal from Canadian boutique maker Fairfield Circuitry. Inspired by primitive vintage transistor fuzz circuits, the ~900 delivers an abrasive, spitting fuzz character with a distinctly gnarly, lo-fi texture that differs from the smooth sustain of Big Muff-style designs. Fairfield Circuitry is known for building characterful, uncompromising circuit designs, and the ~900 represents the brand embrace of maximally distorted, primitive fuzz aesthetics. It suits experimental rock, noise, and heavy garage contexts.
