The Big Muff Pi with Tone Wicker takes the most famous fuzz pedal in the world and adds new tone-shaping capabilities. On top of the familiar controls, the Big Muff Pi with Tone Wicker boasts two switches: Tone and Wicker. The Wicker switch opens up three high-frequency filters, adding top-end bite. Very cool! The Tone switch disengages the Tone control from the circuit, resulting in a full-frontal Big Muff assault like none you've ever heard! For Muff fans, the Big Muff Pi with Tone Wicker is the ultimate fuzz!
