PCB design of a guitar pedal based on the 3rd channel of Diezel VH4 amplifier

goya1746 is an overdrive & preamp pedal based on the legendary Diezel VH4 channel 3. Fully open circuit board designed in KiCad 8. The main idea was to avoid oscillations on all gain levels. This project is shared for hobbyists who want to study, modify, or build their own. The full PCB outline is 115 × 70 mm (4.53 × 2.76 in), but the usable area is about 96 × 70 mm (3.78 × 2.76 in) if you remove the side "wings" in KiCad and define your own edge cut before generating Gerbers. In theory, it should fit a 1590BB enclosure, but keep in mind that each potentiometer is wired separately and the…
