Hadn't done a boost pedal in a while and hadn't done a Lovepedal pedal in a while either, so I'm killing 2 birds with one stone. The Delux 60 uses a Mosfet gain stage set to give clean boost or to push a tube amp into break up. It's simple but effective. This'll fit into a 1590a pretty easily too.
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.
