From the vendor
Wonderfully glitchy octave-down fuzz. Volume does what you think, Filter is kind of obvious, and Blend - well, that blends as much octave-down as you want into your fuzz. Two switches to play with. One flips between one or two octaves down. The other is a footswitch on the original, but we've opted to make it a toggle. This turns the circuit into a random glitch monster that's a lot of fun. The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs. 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. Builds are only available with full kits including enclosure and vertical-mount pots. Please choose appropriate knobs.
