Getting Started Someone asked me about getting started building stompboxes, so I thought I’d put it all in a forum post, for your enjoyment and edification. Become a member of both of these forums. Search, and read what’s posted there.…
This is a really cool service that manufactures open source PCB designs. You can order any of the open source designs on the site. Most of the stuff is not stompbox oriented. It takes a little google-fu to search up…
