Bionic Guzz Fun kit - Vertical format

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

In stock format this is a five-knobber with Level, Fuzz, Filter, Bias and Density controls, as well as a toggle switch to kick in oscillation mode which is more fun than a bucket of badgers. We've added the option of replacing that switch with a pot for adjustable levels of insanity. Though labelled as 'Oscillation', the pot works more like the stability control on a Fuzz Factory, with fully clockwise being entirely un-oscillatey, and more madness being brought forth when the pot is wound back.

You can also opt to have no oscillation control at all, keeping the knobs to a minimal five.

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

Optional extra transistors are available so you can experiment with making it a bit less gated - these are now MPSA06 and BC517 - the results can be a lot more pleasing than the standard cans.

The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs. Pots are spaced 17.5mm apart, so take that into consideration when choosing your 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 only available 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.

It's just a mental pedal. Which is great!
"I've actually built 3 of these now. One in 2014, and I couldn't work out how to use it, then another two in the last couple of months - one to me and one to give to a mate. It's such a cool circuit because it's so unstable and all the controls are interactive, which is great for creativity or forcing yourself out of your comfort zone. None of the 3 I made have sounded quite the same, I'm guessing that's down to variance in the transistors. On one kit I tried the more tame transistors, but switched back to the original wilder ones because to my mind, the whole point of the circuit is that it's a bit insane. It's very heavily gated at most settings, but I find having a compressor or overdrive in front of it gives you a totally useable fuzz sound." Josh - 01 February 2021
