From the vendor

A distortion-tweaker's delight. There's so much tone on tap with this one you'll lose track of time.

From sparkling drive spank to almost fuzz territory, there's enough adjustment on this fella to match it to any setup. Use the Weight knob to fatten up those wheezy coils, or wind it back to tame your fat 'buckers. Twiddle those three-band EQ controls to reach tonal nirvana.

Whack the juice up to 18V for a whole new set of dynamics to play with (from an 18V supply mind you - there's no charge pump on board).

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 batteryKnobs are not included. Pot spacing is tight at 17.5mm so take that into account when selecting suitable knobs.

Builds are only available with full kits including enclosure and vertical-mount pots. Please choose appropriate knobs.
