Electro Harmonix Op-amp Big Muff Pi Fuzz Guitar Effects Pedal (Electro-Harmonix / EHX)
Billy Corgan and James Iha (Smashing Pumpkins) built an empire on Siamese Dream's distinct brand of psychedelia-meets-rock-alternative. A key ingredient to this record's iconic sound, as guitarists today know, is Billy's famed late-'70s V4 IC Big Muff. Now, Corgan and EHX have carefully bottled the tone and response of the original in the Electro-Harmonix Op-Amp Big Muff Pi. This pedal faithfully captures the fuzz-laden and explosive textures of Billy's op-amp equipped '70s Muff. Controls for Volume, Tone, and Sustain (gain) make it quick to dial in the textures your music demands. Meanwhile, a tone bypass toggle temporarily bypasses the pedal's tone circuit for maximum output and aggression. The new compact size and die-cast durability preserve the Siamese Dream tone for a new generation of fuzz fans.
