I built this simple distortion pedal over the weekend for Bálint, the guitar player in Dokkerman. It's the M-104 MXR Distortion from the 70s, the schematics are from this post.
Two notes:
- Be super-careful when bending the legs of the 1N270 germanium diodes. The glass housing breaks very easily.
- I didn't have a closed metal case for the pedal so it started to pick up some AM radio. A
47p
capacitor between the 2nd and 6th pin of the LM741 (so basically parallel with R4) helped.
