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.

Mad Professor Sweet Honey Overdrive

This is a great sounding drive pedal from Mad Professor. Very dynamic and tube-like, the Sweet Honey is a medium gain overdrive that can produce a wide range of tones, from jazz to heavy rock. I've laid the board out for right angle PCB pots mounted from the solder-side of the board, and it should all fit nicely in a 1590B.


  1. I can't hardly hear the difference when I turn the Focus pot around
    anyway, I guess you can mark this one verified dude

  2. It works. Delivered lm833 instead of op275

  3. Built this over the weekend. Great sounding OD. Thanks for the layout!
