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 EarthQuaker Devices Data Corrupter is a modulated monophonic harmonizing phase locked loop pedal that turns your guitar into a wild three voice analog synthesizer. It amplifies your input into a crushing square wave fuzz, then uses a PLL to lock an oscillator to your pitch and multiply, divide and modulate it into stacked sub octaves, octaves and harmonized intervals with square wave modulation. The result ranges from massive synth bass and chiptune leads to glitchy, dissonant, robotic chaos. Monophonic and gloriously aggressive, it suits experimental, synth rock, industrial and adventurous players who want screaming PLL fuzz synth tones, video game textures and unpredictable harmonized madness from a guitar or bass.
The Fairfield Circuitry Unpleasant Surprise is a gated fuzz pedal capable of octave fuzz and extreme gated textures. Controls consist of Volume, Onset (a gain and gate-threshold control), and three toggle switches: T (treble cut), G (gain character — open versus compressed), and C (Crush, which engages octave fuzz). The Onset knob controls the onset of fuzz from raunchy gated artifacts at low settings to beautiful sustained distortion at high settings. The C toggle unlocks a lower-octave harmonic character that combines with the gating for abrasive, synth-like fuzz.
