From the vendor

A wonderfully frightening fuzz.

This is the red channel of the now discontinued Spires dual fuzz pedal, and is their silicon version of the also discontinued Dream Crusher. An apt name for such a bringer of horrors.

Sounds *almost* like the original germanium version, with some very carefully researched (we assume!) and selected silicon BJTs.

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 can take a battery if desired with footswitch positioned 22mm higher, closer to the controls. Knobs are not included.

Inspired by: Spires Red Channel / Dream Crusher

Difficulty: Easy

PCB size: 48 x 25mm

Knobs required: 2

Enclosure: 1590B

Direct Connect compatible (4-way)
