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 Atlas III

Hope everyone's staying safe and healthy. Today's layout is a unique preamp booster from Spaceman Effects, the Atlas III. It uses some FETs I'd never heard of in conjunction with a couple low gain silicon BJTs (use something in the 175-225 hFE range). The switch controls the phase of your signal (it's internal in the original). Schematic can be found here for reference.

Also, I updated the Make a Difference page on the website to include a few funds working to help in the aftermath of the Beruit explosion. It's killed well over 150 people, injured 6000 and left over 300,000 people homeless. If you can, do some good, offer some home and help out some people who are really hurting.
