Description

Pro Tone Pedals OA77 pays homage to the late ’70s era of the Muff we all know and love- the Op Amp era.

The muff underwent a drastic redesign- the transistors were removed and replaced with operational amplifiers. These were made only briefly – a sparse 2 years.

  • Authentic recreation of the late 70’s OA Big Muff
  • True bypass switching
  • Standard 9v center-negative operation
