Electro-Harmonix Op-Amp Big Muff Pi
Effects pedal · United States
The Electro-Harmonix Op-Amp Big Muff Pi reissues the late-1970s op-amp (IC, or V4) Big Muff, which uses op-amps and three gain stages rather than the four-transistor circuit of the classic version. The result is a huge, crushing, scooped fuzz favored for wall-of-sound distortion and heavy rhythm and lead playing, now in a compact die-cast chassis with true bypass and a Tone Bypass switch.
