From the project
A distortion effect pedal I designed.
The PCB is four layers since it so mouch nicer to work with and has become so cheap that two layer PCB are more or less obsolete. I wanted every component to be on the PCB and not having to deal with soldering extra wires to connectors and pots. So when every component is soldered to the PCB, the pedal is essentially done, and just needs to be put into an enclosure. Instead of having a enclosure with art on I designed the PCB to be aesthetically pleasing.
