The BIG MUFF Pi with TONE WICKER is an effects pedal designed to deliver all of the sonic power of the legendary Big Muff Pi while providing user editing capabilities that are unique to the Tone Wicker design. Wicker mode opens up the high frequency bandwidth of your distortion sound delivering a top end that is new and exciting. The Tone switch, when set to OFF, defeats the Big Muff’s Tone knob yielding an extremely powerful distortion with a fire breathing new Big Muff Pi character. • MFSKU TWBIGMUFF
