With original late-70s Op-Amp Big Muffs selling for exorbitant prices, Mike Matthews decided to take the power to the people and reissue the classic pedal at a price that players could afford! The circuitry of the new EHX Op-Amp Big Muff Pi —sometimes also referred to as the IC or V4 Big Muff— has been faithfully re-created while several practical enhancements have been added including a compact, die-cast chassis and true bypass switching.
“The Op-Amp Big Muff was popularized by the brilliant Billy Corgan who first used it on the Smashing Pumpkins’ epic 1993 album Siamese Dream. After he was videotaped playing and talking about the reissue, Billy stated: ‘The magic’s still in the box, I can still get what I’m looking for!’” – Mike Matthews
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.”
- A faithful reissue of the original classic circa 1978
- Iconic sound and vibe that’s coveted by guitarists
- Controls for Tone, Sustain and Volume, plus a Tone Bypass switch
- True bypass switching for maximum signal integrity in bypass mode
- Rugged, compact, die-cast package… pedalboard friendly
- 9V battery included

First pedal in my life.
Of course, at the time of purchase, I was influenced by Billy Corgan. Its not only great for Siamese Dream / Smashing Pumpkins tone, but its also good for grunge, shoegaze, garage rock stuff (Dinosaur Jr. , White Stripes, MBV and others ) One of the greatest modern fuzz pedals. LOVE IT!
Great Big Muff
For about 9 years i've had a Little Big Muff which I've loved. When i started seeing videos that EH was reissuing the op-amp Big Muff, famously used by Billy Corgan and James Iha on Smashing Pumpkins Siamese Dream album, i was intrigued. I listened to some clips, and loved the sound of it. I made it known that it was something i would like and my wife got it for me. Actually playing it i have to say, it blows my Little Big Muff out of the water. It's a tremendous sounding Big Muff pedal. To my ears the Op-Amp sounds a bit brighter, and has a bit more clarity while still giving that Big Muff wall of sound. Not necessarily ideal for drone metal, but otherwise, it's a tremendous pedal.

A thing of beauty
This pedal is a thing of beauty. Was looking to get a Big Muff for a pedalboard I was putting together and after seeing the Billy Corgan demo of the Op-Amp I had to have it. Here's a demo I recorded for music page a few months back (apologies for the dodgy camera, my phone was kinda broken at the time!)
