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.

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.

Difficulty: Medium

PCB size: 100 x 22mm

Knobs required: 5

Enclosure: 1590B, 1590BB

Superb kit, service - the lot! 5 product stars
"Easy build of a great, weird sounding fuzz pedal; really helpful support from Fuzzdog (I got a couple of resistors in the wrong holes) led to a successful conclusion and a lot of noisy fun. In addition, Fuzzdog's PCBs are sturdy and double-sided, meaning that it's possible to desolder components later if you want to try some mods, unlike some other sellers who supply flimsy one sided boards. My second Pedal Parts build and I'm already planning the fourth :)" Francis Blackman - 15/03/2016
