Bionic Guzz Fun kit - Board-mounted version

Build your own clone of a pretty spectacularly uncompromising fuzz monster.

A five-knobber with Level, Fuzz, Filter, Bias and Density controls, as well as a toggle switch to kick in oscillation mode. More fun than a bucket of badgers.

The circuit is a bit picky about the input signal, so this works best without a buffer in front of it.

Available in a few flavours:

• 1590B, single footswitch, mini toggle for oscillation.
• 1590BB, as above.
• 1590BB with a second footswitch for oscillation.

You'll have to sort out your own enclosure if you go for:

There's no option for twin footswtiches in a 1590B - it simply won't fit.

Optional extra transistors available so you can experiment with making it a bit less gated - these are now MPSA06 and BC517 (which requires a leg twist, but its worth it) - the results are a lot more pleasing than the standard cans.

Pots are spaced 21mm apart - take that into consideration when choosing your knobs.

Pots and mini-toggle (if selected) are board-mounted 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 will not take a battery. Knobs are not included.

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