Fuzzy Muff

Very early EHX gain box.

No idea why they called it the Muff Fuzz, as what we have here is actually a low/medium gain overdrive.

Very low part count = simple dirt. Sounds like a vintage tube amp with a worn but warm speaker.

Note: this is NOT a Big Muff Pi. Different thing altogether.

Board-mounted pot for minimal wiring and easy enclosure mounting.

Full kits are available with optional standard sized 1590B enclosure with battery, or a mini 1590A (36 x 90mm) enclosure with DC power only, though be aware that you'll be wiring in a very confined space.


If you want the PCB without parts there's a link for that at the bottom of the page.

Partial kit: PCB, all board-mounted components, pots.

Full kit: As above, plus footswitch and appropriate daughterboard/components for your selected bypass type (see Downloads section for details of those), jack sockets, DC socket, battery snap, hook-up wire, LED.

Enclosure (pre-drilled) is available as an option with full kits, and can take a battery if desired with footswitch positioned 22mm higher, closer to the controls, in a 1590B. 1590A will not take a battery. Knobs are not included.

Builds are only available with full kits including enclosure. Please choose appropriate knobs.

Try out different diodes. 3 product stars
"Really easy pedal to assemble. The stock sound is pretty underwhelming: quiet, slightly overdriven, a little muddy. I took out the clipping diodes and tried it again, and that completely changed the pedal. Removing the diodes turned the pedal into a huge sounding fuzz-distortion with double the amount of volume. I tried out different diodes, but I settled on one of the Russian germanium diodes that came with the kit. One diode tamed the pedal some with only about a 10% drop in volume; two diodes puts it back into sad overdrive territory." awkbinoc - 16 November 2021

Thanks for reviewing. The original is indeed a basic drive, so if it’s not what you’re after it should be avoided. Glad you found a setup that worked for you.
