Ef111ng Craziness

Some things just defy description. We'll give it a go.

It's a fuzz. Kinda. Is it?

Yes, but your fuzzy signal gets mangled through a strange filter section that does all kinds of wild and whacky things to it. What it does depends on the speed and intensity knobs, which fiddle around with the PLL circuit causing filtered chaos. The effect is very much determined by the strength of the signal you send it too, so gentle playing will yield very different results to heavy handed stuff. Basically it's a bucket load of fun, and an absolute must if you like the shoegaze end of tones. Just a quick dig around demo vids should convince you either way.

The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting 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 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 enclosure and vertical-mount pots. Please choose appropriate knobs.
