Enclosure not stated · 3 knobs
From the vendor
There are many Rat clone projects out there, but this one is mine. This is a part-for-part clone of the original Rat circuit. There are no extra pots or switches…just three knobs of ass-kicking tone in a small PCB form factor. It’s laid out for 1N4148 / 1N914 diodes, but you could use pretty much whatever you want to mimic the various Rat version. My suggestions:
1N4148 / 1N914 – Classic Rat
LEDs (diffused) – Turbo Rat
BAT41 or similar Schottky diode – You Dirty Rat (please don’t waste a real Germanium diode on a YDR build)
1x 1N914 + 1x LED – Overpriced boutique Rat variant with an unnecessarily self-aggrandizing name
This board *should* fit in just about any standard enclosure larger than 1590A. The pots are not board-mounted, so you can cram this thing in all sorts of project spaces.

Schematic Image
PCB Image (top layer)
Gerber files (to be used to order a set of PCBs)
Eagle CAD files (for making modifications of your own, if desired)
You can use the zipped gerber files to order from fab houses like JLCPCB , Elecrow, SeeedStudio, and many others. I’m working on a short guide on how to order PCBs, and when it’s done I’ll link it here.
You might also want to check out some of my fuzz-related or overdrive pedal projects.
