From the vendor

If you're after crazy, noisy fuzz you're hit the right page. Based on the Earth Sound Reseach Graphic Fuzz, this box is wild.

The original has some fiddly power requirements, but we've tweaked the circuit so it works with a standard 9v supply so it'll play nice on your chain.

So what does it do? It's a fuzz. A loud fuzz. A huge, bass-heavy fuzz that's absolutely perfect for you doomsters. It also has a wild Filter control that goes from a little colour to all-out resonant squealing like a banshee on a bad hair day. Now, hands up here. The filter doesn't sound exactly the same as the original. Something about giving it 'normal' power changes the nature of it. It's still great, and the fuzz itself is just the same.

This one isn't for the faint hearted, but those with a strong stomach will undoubtedly find a permanent spot on their board for this one.

This latest version includes several options for taming the madness of the filter if you really want to. Check the build document linked below for details.

Board mounted pots for simple enclosure mounting.

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 enclosures. Please choose appropriate knobs.
