The Rat is a superb classic distortion pedal that I expect everyone has heard of. There's a place for it on all pedal boards. The kit comes with standard silicion diodes, but you can swap them for LED's and go Turbo, or if you want total mojo then go Germanium and call it the You Dirty...
This doesn't have too many parts to identify. The PCB design has now changed to one with board mounted pots. I'll update the pics in due course.
This kit is supplied with a JP1590B enclosure.
This kit compares to the original Pro Co Rat.
