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.

Run Off Groove Umble

The Umble is the result of Brian Tremblay's (ROG) adaption the the mythical Dumble amplifier into a FET-based distortion box. I've drawn the layout for on board right angle PCB pots and added a 1N4001 diode for polarity protection. Should fit nicely in a 1590B. Check out the ROG article for more info.

      Forgot to mention that mid pot must be flipped 180
