1978 Electro-Harmonix Big Muff V5 Op-Amp IC Vintage Fuzz Guitar Effects Pedal


+ shipping

Out Of Stock
Up for sale, a 1978 Electro Harmonix Big Muff V5 in exceptional condition and in perfect working order. Produced concurrently with the V3 (and V4!), this early USA-made V5 Muff is unique for utilizing op-amps instead of transistors to achieve the roar and midrange scooped sizzle for which these pedals are known. Identical in circuitry to the V4, the V5's distinction is offering an additional Tone Bypass two-way switch. When engaged, this switch provides a flatter EQ with more midrange content and volume. An aggressive and powerful fuzz, the op-amp Big Muffs are perhaps best known for their extensive use by Smashing Pumpkins.

The pedal features an untouched circuit, with a trio of original CTS pots which date to the 18th week of 1978. The polished aluminum enclosure retains all of the original bold silkscreen graphics and shows only modest scuffing. The back of the pedal is very clean with the shadow of the original small round feet.
