EHX's Big Muff is up there with the most famous guitar pedal to have existed, and rise of its fame stems largely from the usage on Smashing Pumpkin's legendary Siamese Dreams album that inspired a generation of new wave of grunge. Therefore, many guitarists will instantly recognize the iconic sounds of the Op Amp Big Muff, which has appeared on many recordings since its release in 1978. This new and improved version builds on the success of its predecessor along with up-to-date modifications such as a compact, die-cast enclosure, and true bypass switching.


  • A faithful reissue of the original classic from 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 structure
  • Easy-to-use interface
  • Ships with a 9Volt battery, also accepts an optional EHX9.6DC-200 AC Adapter
