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. Shown only within a gear class, and only where there's enough evidence to be meaningful.45% — somewhat different

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 About Nine Hundred is a JFET-based fuzz pedal from the Canadian boutique builder Fairfield, tracing its lineage to the discontinued Four Eyes Fuzz. Two cascading JFET gain stages provide a very wide gain range from gritty, warm saturation to full fuzz with controlled harmonic density. Controls include Input, Fuzz, Bias, and Volume, with the Bias control introducing gated and sputtering textures by adjusting the second stage operating point. It suits blues, psych, indie, and experimental rock contexts.
