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.

Hudson Electronics Sidecar

 Here's a really great sounding overdrive from Hudson Electronics. The Sidecar is loosely based on the Tube Screamer with a 2-band Baxendall EQ and some interesting soft clipping. It uses a PNP germanium as a diode along side an LED and a 1N4148 in an asymmetrical configuration. I've got a fabricated version available in the store as well if you prefer and the schematic is over there in the build doc.

    2. I went with a generic PNP Ge that was originally purchased for a Rangemaster. The circuit works without it but it seemed like the Rangemaster Ge added a very slight tonal coloration.
