From the vendor

Seems like everyone has their own take on the classic Colorsound One-Knob Fuzz, and why not? Like the Electra, the simple design offers a highly tweakable platform that responds well to small changes, making very different sounds availalbe with a little experimentation.

And that's what we have with the HUGE! - ripping fuzz tones for all your doomy needs, with the added benefit of adjustable gain.

After some experimentation of our own, we've found the trimmer offers much more versatility with a small tweak to the original circuit. It's a single jumper on existing pads on the PCB, so not a hack as such. Plus it's simple to remove if you don't like it (oh, you will).

Being a One-Knob Fuzz variant, there's nothing to stop you building any of the other versions on this PCB and having that handy adjustment on tap. Just grab the OKF doc and check out the BOMs.

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 Knob is not included.

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