Electro Harmonix Op Amp Big Muff Pi

A faithful recreation of the famous Op Amp Big Muff Pi. 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.” Made famous by The Smashing Pumpkins.
