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.
Here's another one of Nick Greer's offerings. Like Sean over at Lovepedal, he seems to be getting a lot of mileage out of the Electra circuit. I've laid this out for on-board pots with the board mounted vertically like this:

I saw on the Greer Amps website that a special version of this was made with a BC107 transistor, so use that if you want to replicate the blue version of this pedal.
