Mike Matthews wanted to make the classic Op-Amp Big Muff Pi sound accessible to everyone, so he created the Operation Muffin pedal. This true bypass pedal faithfully recreates the classic circuitry of the original while adding enhancements for a modern sound. It has three gain stages and controls for Tone, Sustain, and Volume, plus a Tone Bypass switch. The Tone Bypass switch allows for maximum signal integrity in bypass mode. The Op-Amp Big Muff Pi sound is described by 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.” The Operation Muffin has three potentiometers for Sustain, Tone, and Volume, as well as a Tone Bypass switch. With these controls, players can create a variety of sounds from the classic Op-Amp Big Muff Pi to modern, unique tones.
