Very early EHX gain box. Revised PCB for 2018.
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.
Kit is available with a 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.
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 only available with full kits, and will (1590B) / will not (1590A) take a battery. Knobs are not included.
Builds are only available with full kits including enclosure. Please choose appropriate knobs.
PCB size: 35 x 21mm
Knobs required: 1
Enclosure: 1590B, 1590A
