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

EHX Op-Amp Big Muff Pi Overdrive Pedal

Op-Amp Big Muff Pi is a faithful recreation of its classic ancestor, the Op-Amp Big Muff. As its name suggests, the pedal makes use of op-amps in lieu of transistors and features three gain stages as opposed to four. The result is a giant sound that is perfect for wall-of-sound distortion and pulverizing leads.
