From the vendor
High gain, gated fuzz for all you filth freaks. Wind the fuzz back for some almost sensible drive tones, or crank it for an absolute splatter-fest
We'll take a guess you can work out Vol, Tone and Fuzz... Add in a Gate control to compress the signal and, well, gate it. Finally a Mix pot blends in your clean signal, so guess what bass-heads? You're covered.
There's also a couple of toggles - Low swaps out one of the transistors for a lower gain and different feel, but honestly, you'd be pushed to notice. Range alters the tone curves and brings a whole new set of sounds to life.
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 will not take a battery. Knobs are not included. Pot spacing is 17.5mm so take that into account when selecting knobs.
Builds are only available with full kits including enclosures. Please choose appropriate knobs.
Inspired by: Haunt Fuzz
Difficulty: Easy
PCB size: 50 x 55mm
Knobs required: 5
Enclosure: 1590B
