This was a originally an SMD 2-in-1 board CultureJam put out. On one side was a Fuzz Face and the other this Tone Bender. So I figured they'd be good Fuzz Friday layouts. They're not on the same board, but either one should fit in a 1590A.
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.
