Zap

Single channel version of the discontinued hybrid silicon/germanium, fuzz beast. The second 'channel' on the original was just a second gain pot - myeh. Build two!

Big gain range will take you from gritty boost to full-on overloaded fuzz madness.

Optional BITE control give you control over the second gain stage bias, so you can push it even further into filth than the original offered.

These will be fairly limited as good NPN germaniums are hard to come by, but we have you covered for now.

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 can take a battery if desired with footswitch positioned 22mm higher, closer to the controls. Knobs are not included.
