Rodent distortion

The Rat is worthy of a place on any pedalboard, and comes in several flavours to satisfy most tastes.

This kit has spots for two separate clipping diode pairs so you can switch between two different models in an instant, though one pair can be hardwired if you want to ditch that option.

Diodes are supplied for the Standard model (silicon) and Turbo (LEDs) as standard, with the germamiums for the You Dirty model being optional.

Kit is supplied with OP07. Our stash of vintage LM308 is gone.

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

IMPORTANT NOTE: You can't build a three-knob version with vertical mount pots AND use the board-mounted clipping selection switch. For a three-knob version with clipping selection you have to wire the switch. Sorry.

If you go for vertical pots please note they have a round shaft - you'll need knobs with set-screw fitting.

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 (depending on selected options), 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 enclosure and vertical-mount pots. Please choose appropriate knobs.

The RAT design is legendary for a reason
"I built my awesome RAT clone circuite into a 1590B enclosure with all the optional clipping mods. The Standard RAT, Dirty RAT and Turbo RAT options make this worthy of 5 stars all day long and I wouldn't leave home without it (for all genres)..." XcLeB - 09 December 2022

Exactly what you'd expect
"This sounds exactly like you'd expect it to sound - it's such a flexible pedal, will give you everything from early Foo Fighters to Blur to Thrice etc etc depending on your rig. For my taste, anything that takes it away from the original circuit removes some of what gives it its character - so I ended up disconnecting the response pot & replacing with a fixed resistor after I set it by ear then measured that I'd set it to 51ohms. And while the LED clipping is louder, I think once you volume match the two settings I prefer the stock diode clipping." Josh - 01 February 2021
