Three different muff fuzz circuits, selectable with a 3-way toggle switch.

Add to that a tone-bypass option, then feed it all into an active Mids Overdrive that you can kick on and off at will.

Remember when muffs were rumored to be made of scrapped Soviet tanks? Well, the 3MuF-14 might as well be a control panel ripped out of the cockpit of a MiG jet.

  • 3-way selectable muff circuit (Black, Green, and Civil War)
  • Tone bypass toggle
  • Built-in mids overdrive
    • Internal trimpots to tweak the mids drive voice
    • Socketed opamps and transistors. Experiment with different components to customize your pedal.
  • Heavy-duty construction with metal faceplate, aluminum toggle guards, and individually numbered and signed units.
I love distortion.  I agonize over which distortion gets a spot on my pedalboard for a certain band, or even a certain show.  A Civil War when I play bass.  A tall-front Green with unreal bass response for a stoner/doom show. A "bosstortion" with a tone bypass mod for an open-sounding So-Cal distortion sound.

Why can't I have it all!?  Oh wait, I build pedals... I can have all three in one box and have room for extra goodies!

This is a heavvvy distortion/fuzz that I'm sure you're familiar with, but I've brought a ton of new features along for the ride:

  • select among 3 famous circuits
  • tone bypass toggle so you can just hear the distortion/fuzz circuit alone
  • modeled after the cockpit controls of a Russian MiG jet
  • stamped serial numbers on the metal faceplate of all pedals
This circuit typically has a significant mids cut when the tone circuit is engaged, so some players opt to run it into an overdrive with a mids spike to even things out for new tonal possibilities.  Well, fam I got you covered.

The second footswitch is an in-pedal overdrive placed after the tone section of the main distortion circuit.  A Trim control lets you keep the overdrive's volume equal to your fuzz's volume, and two internal trimpots let you change the character of the voice of the drive.

Internal features:

  • socketed components
    • swap your clipping-stage transistors from the original 5888s
      • Try 5889 for slightly more gain
      • Try 2N222 for a choked-out overdrive sound
      • Try BC547 for a more vintage sounding distortion
      • And more!  I'd love to hear what you come up with
    • socketed Mids Drive opamp
      • I ship it with a 4558 for a vintage overdrive sound
      • Try TL072 for vintage but crisp sound
      • heck, try a NE5532 for modern hi-fi sound... Mr. Moneybags.
  • Mids Drive drive level
  • Mids Drive tone control
Basically, it's your favorite distortion, but so much more flexible.
