Warthog

Op-amp based overdrive and distortion with Burr-Brown op-amp and enormous gain range—from crystal-clear boost through overdrive and distortion to touch-sensitive fuzz at extreme settings. American-voiced gain character rather than British.

Gain, Calibre, Tone, and Volume controls. The unique Calibre knob adds girth and harmonic complexity mimicking tube amp saturation response. Tone sweeps between bass-heavy and treble-heavy. Volume at unity varies with gain setting.

Covers clean boost (low Calibre, low Gain, high Volume), overdrive, distortion, and fuzz territory from a single pedal. The Calibre control is unique to this design, providing a second dimension of tonal shaping. 1% metal film resistors, WIMA and Panasonic capacitors. 25mA draw, 65mm x 125mm x 53mm.
