The Open Source Guitar Pedal
September 29, 2025
Project Guides
The FunBox v3 is a DIY, open source guitar pedal that you can build yourself. Keyth, aka GuitarML, built this project and was kind enough to share it with the world. I decided to take on this project a build a few of these for myself, and I made a video about the whole thing!
I also build a project guide in case this was something you wanted to try as well.
