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.

Dusky Electronics Hypatia

For Fuzz Friday this week I give you the Dusky Electronics Hypatia. It's based on the Bazz Fuss, but with a whole lot more control added gain stages and buffers. Should fit nicely in a 1590B. Here's the schematic for reference.


  1. Hi, this layout has been verified. For power filtering, I've added 100nF multilayered ceramic cap to the red line from 9v input, and ignored 100uF elec cap on the right-side bottom. Very nice sound, thank you for this great layout!
