Frequently Asked Questions

Orders under $50 incur a minimum order fee to cover shipping.

Standard vs Express Shipping

Our shipping platform will automatically determine and display the Express or Standard shipping options that are available to you. If Express is not displaying, you're either located too far away from our store in Canberra, or the Standard shipping option will get it to you just as fast for the same price. Express shipping is 1-5 days, Standard 2-10 days depending on how far you are away from our store in Canberra.

    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 Op-Amp Big Muff —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.”

    Quick Specs

    • 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
    • Optional power supply available (not included, 9VDC centre negative)
    • Rugged, compact, die-cast package… pedalboard friendly
