From the post
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.
