Big Knob Pedals I.C.B.M.


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
