Poltava DOA Muff

Not your average Muff: the DOA delivers unique grit and tonal shaping



Poltava DOA Muff is our take on Op-amp Big Muff circuit; it has a unique texture of fuzz/distortion due to the usage of discrete op-amp (DOA) for the gain stage, and different clipping arrangements. However, it's not just a clone but an improved version with true bypass, Big Muff or Filter EQ, and an input impedance switch.


  • Sustain - the amount of gain.
  • Volume - output level.
  • EQ - depending on EQ toggle position controls the balance between high and low frequencies or hi frequencies only.
  • Impedance toggle - "Classic" - ~56k ohm input impedance similar to EHX Op-amp Big Muff, "Custom" - ~1M ohm, high impedance.
  • EQ toggle - switches between classic Big Muff tone stack or Rat-ish lowpass filter (doesn't scoop the mids).
  • LED brightness trimmer - placed on the PCB trimmer allows you to adjust the status LED brightness.
