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.

High quality and sounds great

My search for suitable dirt tones has led me explore to the world of fuzz. I purchased a few affordable overseas pedals, and though better than the fuzz found on my digital multi-effects, something was missing. Well, here it is. This pedal was very reasonably priced, but was an order of magnitude better than my other pedals. Quieter, and it doesnt send a bone rattling click through my 100 watt tube amps when I turn it on. The sound is amazingly rich, and I can play full fuzz chords. They even provided the wall wart!

Bigmuff Pi Op-Amp is a beast!

The fuzz tones are insane in and out of the op-amp position. Very usable tones from this little killer of a pedal. Want Sabbath tones? Got it! Want Hendrix tones? Done! Get tones from the Knack to the Smashing Pumpkins and anywhere in between. This has a tight response and very musical sounding with both single coil and hum bucker equipped guitars. Sounds fantastic through a clean or over driven sound. It loses a lot of character through a distortion tone but still can get a good tone if the distortion and fuzz are blended and EQued a bit. Definitely a fun pedal to have. Absolutely love mine.

Best fuzz on the market

Classic fuzz that can't be beat. Pairs very well with my overdrive pedal as well, produces rich and creamy fuzz a la Gish era Smashing Pumpkins. It's a must have for sure!

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.
