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

Ups! I forgot the pictures in my last post.

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.

Hi George,

Thanks for looking closely you are right.

Georg Giblet recently found a fault in the input circuitry of the Reagun overdrive, thanks again.
While tracing the layout I found two more faults and have corrected the schematic.
The input circuit part of the Reagun Distortion is identical to that of the Overdrive and was also wrong in its schematic and had to correct it.
I am sorry.
Corrected schematic:
