Electro Harmonix Bass Big Muff Pi

The classic three-knob design of Volume, Tone, and Sustain make for familiar control over the fuzz circuit. A Dry/Bass Boost switch either mixes you dry signal with the fuzz tone or reintroduces more low frequencies into the fuzz circuit, which is useful when the Tone knob is set high. A seperate Dry output allows for two amps sets for increased setup versatility.
