Big Knob Pedals

Confirmed from sources as the muff circuit Billy Corgan used for his "Siamese Dream" guitar sound, this pedal is cloned from the exact same 1977 opamp-based model used on the classic album. This version was the first muff to break away from the traditional four-transistor circuit design, using instead two opamps (a LM741 and JRC4558) that yielded a crunchier hi-gain twist to the classic fuzz.

I.C.B.M. features:

  • A circuit replica of Corgan's 'Siamese Dream' opamp-based muff
  • LM741 and JRC4558 opamps just like the original
  • Controls for Volume, Tone and Sustain
  • Fully hand-wired analog circuitry
  • Compact MXR-sized enclosure
  • True bypass 3PDT switching
  • Bright indicator LED
  • Accepts standard 9V pedal adaptor
  • 9V DC battery clip included
