Sporting a rugged steel chassis, knobs for volume and saturation onset, and a wild triumvirate of gain, treble and compression knobs for a wide spread of grinding, experimental tone, the Fairfield Circuitry Unpleasant Surprise presses gated fuzz past all convention for one of the strangest and most inventive pedals on the market. Reminiscent of a robot gone AWOL or a buzz saw hacking through a circuit board, this little monster is the perfect addition for any bass, guitar, or synth player who thinks "abrasive" isn't far enough.
