Zonk II

JHS's bargain offering that was touted alongside their germanium Zonk Machine. Absolutely completely different beasts. Utterly.

This bad boy has more in common with a Fuzz Face than the ZM, but different enough to sit side by side with the king of two-transistor fuzzes.

We've changed things up a bit to make this a nicer package - improved volume control, optional miller caps on the transistors to avoid high frequency oscillation, and that signal-killing 2M2 on the output reduced to 220K to get your volume where it should be. We'll send a 2M2 anyway if you want to keep it closer to stock.

Of course, the original transistors are obsolete, so after some experimentation we've gone for 2N2222. They feel right.

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.
