From the vendor

NOTE - PCB has been updated. The toggle switch that was between the two pots has been moved up 4mm so things are less cramped.

If you like your fuzz raw, splattery and face-meltingly intense this one's for you.

Two different flavours can be built - standard (if that word even applies to this fuzz), and vintage master, which has a pronounced octave-up. The only difference between the two builds is reversing a transistor, and you can do this with the flip of a switch if you want both on tap. In either guise your amp will feel like its been on the wrong end of a red hot poker.

You can also add the 'chaos' switch if you like. This makes the whole thing sound like it's down a K-hole and isn't happy about it at all. Not for those looking for pure tone.

Caution: This is not a clean, quiet effect. It's a beast, and as such has noisy fangs.

Board-mounted pots for minimal wiring and easy enclosure mounting.

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.

Builds are only available with full kits including enclosures. Please choose appropriate knobs.
