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.

Lovepedal Dover Drive

Here's a pretty interesting overdrive from Lovepedal (Hermida). The signal goes through a dual PNP silicon transistor stage (don't worry, it's still a negative ground effect), then into a op amp gain stage with soft clipping in the feedback loop, with a Rat-style tone control, followed by an output buffer. Schematic can be found on FSB for reference.

  1. I wonder what happens if you throw germanium pnps instead of silicon ones. Will definitely check.
    ty for the layout

    1. I'd be interested in how this goes... need to do something with some spare 2n404a

  2. I installed old Soviet germanium transistors (q1-mp42b h21 = 82, q2-mp41a h21 = 129). The sound is very cool. Warm and saturated sparkling )))

    1. Diodes are also old Soviet germanium d9b instead of 1N34a
