Complete audio effect stompbox ecosystem and collection of designs
This is a convenient system for quickly creating stompboxes, as well as a collection of designs made with this system.
The design is split into two boards, a lower and an upper one. The lower PCB handles all of the I/O, switching, and power stuff, while the upper one focuses on the individual effect. The two boards plug together and fit neatly inside a commonly used Hammond 1590B. For each finished design there is also a PCB frontpanel so I don't have to deal with any actual design work and can just hide my designs behind technical looking stuff. The actual boards take full advantage of…
