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.

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

We're no longer selling these with the transistors found in early units. They were far too unpredictable and could yield results that were gated beyond use. We now supply MPSA06 and BC517, giving an altogether more pleasant experience.

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
