Fairfield Circuitry The Unpleasant Surprise
Fairfield Circuitry · pedal
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.
