Guitar pedal starter template based on project by Mark Wu. Includes schematic and PCB layout for basic DIY pedal hardware. This includes two 1/4" jacks (one for input and one for output), a 9V power supply, a 3PDT true bypass wiring setup, and an example potentiometer that can be copy/pasted throughout the circuit. size is a good default size for a 125B enclosure. The headers are meant to be unpopulated so that wires can be soldered to the pads. PCB design rules imported from the JLCPCB 2-layer stackup template. Meant to be used with the 3PDT Breakout Board on my profile. #template
