Effects pedals and stomboxes
All components are standard and generic. Gerbers for PCB are in the repo 1 2, as well as case graphics and drill locations which can be ordered on Tayda. Cost of components are around $40 per unit at small quantites.
1. Solder silicon components (BJTs, diodes) except LED. 2. Solder capacitors except electrolytic. 3. Solder resistors. 4. Add leads for power. Keep them long, you can always make them shorter later. 5. Solder jacks, to the back side of the board (the opposite side from the components). Make sure they sit flush with the PCB. 6. Place the potentiometers in the PCB, but don't…
