From the vendor

'Transparent, dynamic...'. We've heard it all before, so let's cut to the chase.

Loosely based on a Tube Screamer, with a nicely tuned James (or Baxandall if you like, though that's active, not passive) tone stack. It just works.

Great range of grit, from light drive to full distortion. Stick it in front of a tube amp with light break-up and it'll make it sing.

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

If you opt for top mounted jacks you'll receive Lumberg sockets. The lugs need to be carefully bent back so they don't short on the enclosure. Be aware you'll be wiring in a tight space. Top jacks cannot be combined with battery provision.

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.
