Electro Harmonix OP Amp Big Muff Pi Fuzz - DISTORTION EFFECT / SUSTAINER PEDAL FOR GUITAR

(This text is machine translated) With the original Big Muff from the late 1970s on sale at exorbitant prices, Mike Matthews decided to re-propose the classic pedal at a price that players could afford. The circuits of the new Op-Amp Big Muff - sometimes also referred to as IC or V4 Big Muff - have been faithfully recreated while adding several practical improvements including a compact die-cast chassis and true-bypass. The Op-Amp Big Muff was popularized by the genius Billy Corgan who first used it on the Smashing Pumpkins' epic 1993 album Siamese Dream. The pedal relies on op-amps rather than transistors and three gain levels instead of four, to create its signature sound.
