This is the first of a few PCBs I've had a go at putting together myself using DipTrace and JLCPCB. Massive thanks to @cooder firstly for the inspiration with his amazing builds and for helping me get my head around DipTrace.
This is a rat that uses some of Jack Ormans mods from his e-book. I wanted to have a go at building one after @thewintersoldier & @Big Monk got talking about rats. Also I loved @jimilee different clipping options on his build. This build uses a 2P4T on a breakout board to allow for soft clipping, hard clipping, LED clipping and no clipping. Hard clipping is switchable internally between symmetrical and asymmetrical. I also managed to get hold of a genuine LM308 for mojo points.
The PCB sits on top of the footswitches so I have had to use pots with the long pins. There is a JFET boost after it on the 2nd switch which is great to just push the amp into more distortion. I have used coda micro controller based relay bypass switching which was a PITA to program the PICs but after lots of failures it worked. Thanks @dan.schumaker for the hex file.
