While cleaning up I found this incomplete Reagun Distortion that I bought years ago.
Anyway, now I have traced it.
Here the PCB layout and the schematic, some measurements come later.
This is the same PCB as the REAGUN Overdrive but partly with other, omitted and additional components

During the repair I found an error in the schematic, the resistance between terminal 5 of the OP-amp and the 4.5 volt point has a value of 470 Kiloohm and not 22 Kiloohm.

The 10n on the switch probably connects to the 1k and ground. The 2x220p connects to the 1k + 10n + 1M point.
