I've drawn up 2 different boards–both have the LED and the LED resistor on board, but one has a MAX1044-based charge pump for when you're building a positive ground effect. It has polarity protection and power filtration on-board as well.
This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.

3PDT Footswitch PCBs
Got a request for a PCB to make wiring up 3PDT footswitches a little less messy. There seems to be about a dozen ways to actually wire up an effect with a 3PDT, but I went with this wiring scheme drawn up by Bumblebee over on DIYStompboxes as it's fairly neat and efficient. The effect input is grounded with the effect is bypassed, which eliminates any oscillation that might happen in pedals like the Small Stone.
