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.

Exar OD-2

 Here's a fairly unique OD from the mid-nineties and the Polish pedal manufacture Exar Electronix. It's a soft clipping drive based around a simple discrete opamp topography. Originals have J113 JFETs, but others should work just fine. More info on FSB.

  4. It looks like the OD-4 has an additional "turbo" pot. Any ideas on what was added between the OD-2 and OD-4?
