This is a vintage 1974 Electro Harmonix Big Muff electric guitar effects pedal. This Ram’s Head V2 Big Muff fuzz pedal, features the rare and super desirable (4) PNP 2N5087 transistors, and is a particularly great-sounding example. While the EH 3003 PCB trace pattern circuit remains identical for all V2 Big Muffs, the components vary widely, which means they all sound unique. Having owned more than most, I can say with confidence that this example is the best I have heard, and is 1 of only 2 I have offered with the aforementioned transistor.
As the photos illustrate, this particular example is in very excellent 100% all original condition. The exterior graphics are quite clean and crisp. The case does not exhibit normal oxidation and displays only very minimal superficial wear. Even all (4) original rubber feet are intact and still affixed to the bottom of the pedal’s vinyl-textured bottom case.
From David Gilmour to J. Mascis, the Big Muff has been an integral part of great classic guitar tone.
