I bought the pedal for a reasonable price.
The tracing showed that the pedal is a one-to-one copy of the Boss SD-1 circuit except the BJT-transistor types and the tone pot characteristic.
I replaced the Boss componet names by the VShock Super Overdrive names in the original circuit in accordance with the PCB imprint.
The pedal are offered with different brand names:
Century SD-10 Super Over Drive
Denio SD-10 Super Over Drive
Dixon EP-10 Super Over Drive
Lazer SD-10 Super Over Drive
Marathon Super Over Drive
Maxtone OD-10 Super Over Drive
Maxx OD-10 Super Over Drive
Rockson OD-10 Super Over Drive
Session SD-10 Super Over Drive
I made a PCB-Clone to easier find differences:
It might just be helpful for repair on the pedals.
