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.

Spaceman Effects Saturn V
Here's the Spaceman Saturn V boost pedal. It's a pretty unique booster and uses depletion mode LND150N3-G MOSFETs. In original units, there are 2 resistors in series going to each drain of the transistors. They essentially create a 4.7k resistor using some really uncommon values. (It appears that the only reason for that is for more interesting guts. And lets be real, Spaceman has some of the best looking pedal guts around.) I've included room for the ferrite beads of the originals to fit on the board (these reduce RF noise) and if you wire the pots off board you can probably fit it in a 1590a. More info and schematic found here.
