Stink Drive

Madbean's excellent take on Aron Nelson's Smash Drive.

Of course, there was nothing wrong with the original - a high-gain 386-based power amp box of chug, but Brian has added a little bit of highly useful magic.

The highly effective TMB tone stack is a joy to tweak, and covers a lot of different distortion tones. This is followed by a FET buffer to keep the output in check.

Five knobs of filthy fun.

Available with either through-hole or SMT FET for those of you comfortable with those tiny parts.

The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs. Pot spacing is very tight (17.5mm), so you'll need small knobs. 1900H fit well.

If you opt for top mounted jacks you'll receive Lumberg sockets. The lugs need to be carefully bent back so they don't short on the enclosure. Be aware you'll be wiring in a tight space.

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.
