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.47% — somewhat different

The EarthQuaker Devices Fuzz Master General is an octave fuzz pedal from EQD, based on the Ace Tone FM-2 Fuzz Master circuit, which shares heritage with the Super-Fuzz design. The Fuzz Master General features a three-way toggle switch for selecting between germanium diode clipping, silicon diode clipping, and no diode clipping, alongside a variable tone-shaping Tone knob. This diode switching system produces three distinctly different fuzz characters from a single enclosure: the softer compression of germanium, the harder response of silicon, and the most open, raw character with no clipping diodes. The upper-octave harmonic content of the Super-Fuzz-inspired circuit adds a distinctive, singing octave quality to sustained notes.
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.
