What Filter? Fuzz

Nice take on making a silicon Fuzz Face more versatile.

It has the basic FF topology and adds a pot at the input to limit the frequencies hitting the fuzz, tightening things up, or open it up for full range fun as per the original.

What makes it interesting is the filter function. The original has this as a footswitch, but we've made it a toggle to keep things neat in a 1590B. It's easy enough to wire up a footswitch offboard if you think it'll be more useful.

The second toggle - a three-way - selects what the filter does to the mids, accentuating the upper, middle or lower mids for pretty different resulting sonic sweetness. This is a rotary on the original, but we really try to avoid them where possible. You get the same three sounds on the toggle.

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 enclosures and vertical-mount pots. Please choose appropriate knobs.
