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.
Almost identical to the BearFoot BlueBerry Bass Overdrive, this version is tuned for guitar. A medium drive apparently inspired by old Supro amps, it delivers warm overdrive that's very sensitive to your pick attack.
