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! Has velcro on the bottom. With Box. Very Good.
