From the vendor

High gain distortion without the mush.

CMOS-based dirt that retains clarity and let's your tones sing. How does it do it? Dunno, but it works. Hear those individual strings spank while cranking your speaker. Great clean-up too.

The original values in the circuit are super-tight, giving a thin, piercing tone that'll cut the thickest mix. We'll include a few substitition parts for the 'Modern' version of the pedal that was released as a limited edition, which thickens things up a bit and makes it a more versative box.

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.

Inspired by: Stone Grey Distortion

PCB size: 50 x 40mm
