From the vendor

Delightfully doomy drive loosely based on the preamp of the Orange OR-120 - monster 70's amps with a distinctive growl.

Tuned to work well with standard guitar, drop tuned sludge machines or even bass, with a wide range of tone on offer. Dial back the gain for a little hair and tweak the tonestack for your listening pleasure. Crank the gain and you're into full-on fuzzy saturated sounds.

Available with through-hole or SMT FETs, for those with a steady hand who want to save a few quid.

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.

Inspired by: FET120 Overdrive Preamp

Difficulty: Medium

PCB size: 50 x 40mm

Knobs required: 4

Enclosure: 1590B

Direct-Connect compatible (4-way)
