Other key parts include the PT2399, TL072 and L78L05_TO92. By type, the board carries 22 capacitors, 19 resistors, 3 ICs, 1 connector and 1 diode.

It belongs with the audio designs in this gallery.

From the project

collection of guitar pedal PCB layouts in kicad

Current count of pedals in this repo is: 34.

The latest change is to add a PDF in the root of each pedal directory, which has the readme, the schematic as an image, and the front and back layout of the PCB (F.Cu+F.Silkscreen, B.Cu+F.Silkscreen). Also a BOM of the parts is included. This was all done scripted using kicad-cli in a VM (Fedora 44, Kicad 10 !!!) as the Kicad 7 versions of this did not work very well. I will add pics of the real tested boards as an addendum to these. This change was a result of some feedback I recieved about the lack of clarity of what is in this repo.
