Electro-Harmonix Reissues the Op-Amp Big Muff Pi

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.

New York, NY (December 12, 2017) -- Electro-Harmonix has reissued their late 1970s Op-Amp Big Muff Pi. 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.

According to Electro-Harmonix founder, Mike Matthews, “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!’”

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.

The pedal is available now and carries a U.S. street price of $80.90.

A blind horse wouldn’t be impressed, but this beautiful, double-horned instrument with one-of-a-kind engravings helped make luthier Tony Zemaitis famous.

Though they never reached the commercial success of some of their peers, the Faces have no doubt earned a place as one of the seminal rock ’n’ roll bands of the late ’60s and early ’70s. Combining influences as varied as instrumental funk à la the Meters, traditional folk music, and a heavy dose of rhythm and blues, the Faces brand of rock ’n’ roll can be heard in some way or another in the music of countless bands that followed. After the Faces folded in 1975, all five members went on to continue making great music, but their chemistry together was undeniable.

Oh no—it finally happened! Now the big question: How long before my verve for guitar recovers from Covid?

This past Sunday I awoke to a very un-Sunday sensation. Hovering on the edge of consciousness, as yet still incapable of contemplating what Sunday mornings are for (lounging in bed till coffee’s made and lunch plans are set, of course!), I was suddenly struck by a godawful stench. As one does, I wrinkled up my nose, lifted my head to look around in disgust, and took a couple more sniffs to see if … I don’t know—maybe I’d dreamt it? Or woke up incontinent? Then I tasted the putrescence. Then … nothing.

Fuuuuuuuck.
