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.48% — somewhat different

The EarthQuaker Devices Bit Commander is a boutique analog octave synthesizer and ring modulator from the Akron, Ohio builder, producing square-wave sub-octave, octave, and two-octave harmonics alongside the fundamental signal for aggressive synth-like tones. Controls allow adjusting levels for each harmonic and a gate control shapes the synth response. Best for single-note melodic applications; chords produce unstable tracking. Suited for experimental, stoner rock, funk, and players seeking radical synth-like octave tones.
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.
