Electro-Harmonix Op-Amp Big Muff Pi
Fuzz
The Op-Amp Big Muff Pi recreates the op-amp Big Muff design from the late 1970s.
It uses op-amps rather than transistors and provides Tone, Sustain, Volume, and a tone-bypass switch.
Its crunchy, dense distortion works for heavy rhythm guitar and layered wall-of-sound leads.
