Electro-Harmonix Op-Amp Big Muff Pi Fuzz/Distortion/Sustainer Pedal

Faithful re-creation of the original late-70s Op-Amp Big Muff Pi!With original late-70s Op-Amp Big Muffs selling for exorbitant prices, Mike Matthews decided to take the power to the people and reissue the classic pedal at a price that players could afford! The circuitry of the new EHX Op-Amp Big Muff Pi -sometimes also referred to as the IC or V4 Big Muff- has been faithfully re-created while several practical enhancements have been added including a compact, die-cast chassis and true bypass switching.The pedal relies on op-amps rather than transistors and three gain stages rather than four, to create its signature sound. It's a sound that's been described by noted Big Muff collector and historian, Kit Rae, as: "a huge, crushing Big Muff sound with more crunch... great for grungy, wall-of-sound distortion, heavy rhythm playing and heavy leads."Volume ControlSets the output level.Sustain ControlAdjusts the amount of sustain and distortion.Tone ControlProvides a range of sounds from high treble to deep bass.Tone SwitchRemoves the TONE control from the circuit.Footswitch & Status LEDToggle between effect and bypass modes. When the LED is lit, the effect is active.Input JackThis is the audio input.AMP JackThis is the audio output.
