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.
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.
