Up for sale is a vintage Electro-Harmonix Big Muff Pi V5 (EH3003 PCB) — the sought-after IC / Op-Amp version famously associated with Billy Corgan’s massive fuzz tones on Siamese Dream and widely used throughout the grunge and alternative rock scene of the late ‘80s and ‘90s.

This is the desirable EH3003 board version, known for its aggressive, saturated sustain, cutting mids, and tighter, more articulate fuzz character compared to earlier transistor Big Muffs. Think huge walls of fuzz, sustaining leads, and that unmistakable alternative rock roar.

Condition:

• Fully functional
• Very good cosmetic condition for its age
• Clean original faceplate with normal vintage wear
• Pots and switch functioning properly

The pedal sounds exactly like you’d want a vintage IC Big Muff to sound — thick, sustaining, aggressive, yet surprisingly articulate.

A fantastic piece for collectors, Smashing Pumpkins fans, grunge/shoegaze players, or anyone chasing classic ‘90s distortion and fuzz tones.

Please review photos carefully for condition.

Packed well and shipped worldwide!
