Built in the image of the coveted late '70s models made famous on the Smashing Pumpkins' enormous album Siamese Dream, the Electro-Harmonix Op Amp Big Muff Reissue Fuzz summons iconic '90s snarl in a compact chassis. Renowned for its enormous, biting presence thanks to the presence of op-amps instead of transistors and three gain stages instead of four, this much-demanded Big Muff is a fast, affordable avenue to the vicious tone of a company classic.

    Have had a variety of Big Muff pedals over the years. Starting to pick up some of the re-issues now & this is my favorite of those so far. It found it's way on a CD within a week of arriving.

    Great little stomp box. Built like a tank. Wish it were a bit more grungy rather than smooth, but I’m still tweaking things.

    Came with paperwork and box. Also included a 9 volt battery. As advertised. Would buy again! That Smashing Pumpkins/Sabbath sound.
