From the vendor

Nice range of fuzzy tones from this one, from a bit of dirt to full on ripsaw, with some nice doomy filth in the middle.

The Starve control is actually the opposite, in that you have full voltage with the knob fully CW. Maybe call it UnStarve? Nah. Name aside, the control is pretty awful with the 100KA pot on the original. We highly recommend going for the smaller value reverse log for a much more useable range.

The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs. There's plenty of space going on in the enclosure, so we've added the option for a top-mounted DC socket if you prefer that to the usual side-mount.

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. Please choose appropriate knobs.
