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.

Glass Jaw

Fuzz Friday! Here's a cool one designed by Alec Breslow (check him out on Instagram) who was cool enough to share his schematic. It's based on the EQD Acapulco Gold with an added blend control and Baxandall EQ. Good for both bass and guitar. It's laid out for board mounted pots an will fit nicely in a 1590B.

Here's the schematic for reference:


  1. Ive try to search for samples of this, but could not find any. Can u give link to some audio or video samples please?

  2. i gotta tell you this site is friggin awsome...big thank you from fl.

  3. Verified!

    I wouldn't bother with a battery clip for this one, tested it with a 9v reading at 7.75volts and it couldn't power the ICs.
