Electro-Harmonix has reissued their late-70s era Op-Amp Big Muff Pi that was popularized by Billy Corgan of the Smashing Pumpkins during the early 90s. Sometimes also referred to as the IC or V4 Big Muff, the original circuitry has been faithfully re-created while several practical enhancements have been added including a compact, die-cast chassis and true bypass switching.

The pedal relies on op-amps rather than transistors and three gain stages rather than four, to create its signature sound. It’s a sound that’s been described by noted Big Muff collector and historian, Kit Rae, as: "a huge, crushing Big Muff sound with more crunch...great for grungy, wall-of-sound distortion, heavy rhythm playing and heavy leads."

The Op-Amp Big Muff Pi features standard controls: Sustain, Tone and Volume, plus a Tone toggle switch for bypassing the tone circuit. It comes equipped with a 9V battery or can be powered by an optional 9-volt AC adapter.

Siamese Dream in a box

Classic Mu££ tones in a stylish compact packaging. A little harsher than the classic mu££ and not as loose as the Russian one, Nails mid-90s smashing pumpkins fuzz tones

Great tone, but bad fit for bass

Experimented using this pedal with bass. It absolutely screams. Really fun playing by myself. However, when playing with a band, I got buried in the mix. Might work OK for bass with the assistance of other pedals, but it simply did not work with a band.

Fuzzzzzzzzzzzz.....

This is a good fuzz pedal, you can make quite a racket with it. Its better than the TC Electronic Rusty Fuzz that I traded in on it but not as good as the Wampler Velvet Fuzz. Price is in between those two others so it's a fair deal. Try it, you might buy it.

Smashing Pumpkins in a box

I love this pedal. I'll say it again. I LOVE THIS PEDAL. I have been such a huge fan of the Smashing Pumpkins for so many years. This is literally the gateway to the early years of Mr. Corgan's tone. This will give you the thick and creamy fuzz tone you've been Siamese Dreaming of. This pedal uses an op amp circuit which allows higher input impedance, lower output impedance, and higher gain than a circuit built on transistors.
