This is one absolute beast of a circuit.
Four-knob box of ear-splitting fuzz. Utterly uncompromising. Fuzz control goes from zero (very, very fuzzy) to ten (broken-speaker crackle fuzz).
Though actually a bass fuzz, this is just as good on guitar, and sounds unlike anything else out there.
Most layouts for this pedal have a hefty amount of fiddly and confusing pot connection. This kit has all the madness contained within the PCB, so much simpler to get to grips with. Those board-mounted pots take all the headache out of this build.
If you want to make a version with a different pot configuration take a look at the wired version of the kit.
There's also the option of going for a 5K reverse log pot for the Fuzz control which gives much better range and sweep than the original 2K linear.
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 not take a battery. Knobs are not included.
Builds are only available with full kits including enclosures. Please choose appropriate knobs.
