Selling a completely original, vintage 1978 EHX Big Muff Pi V5 with the Tone-Bypass switch. This is the highly sought-after EH1322 circuit board variant that uses operational amplifiers (Op-Amps) instead of traditional transistors—the exact circuit famously used by Billy Corgan for the wall-of-sound guitar tones on Smashing Pumpkins' Siamese Dream. 100% Original: Pristine internal wiring, original parts, and the factory battery foam is still intact.Dating: Pots are stamped 13778XX, verifying a 1978 production year.Condition: Excellent working order. Case is structurally perfect and all controls work flawlessly. Price: $550
