The circuit matches the full-size Big Muff Pi without changes to its sound. That means long, singing sustain with the familiar Big Muff fuzz character. The compact die-cast chassis is built to survive heavy use on the floor.

Three controls cover the whole pedal. Sustain sets the amount of sustain and distortion. Tone sweeps from deep bass to high treble, and Volume sets the output level. Bypass is true bypass.

Jack placement follows the Big Muff layout, with the Amp output on the left side and the Input on the right. EHX sells it in its Big Muff range alongside the full-size Big Muff Pi.
