Voodoo Lab

HNY 2019 to everybody!

I am a new kid in the forum and need some help.
I just bought a used Voodoo Lab Micro Vibe pedal.

I has been modded by the preowner and I want to put it back to the original state.

Could someone please send me a schematic?

Or just help me to find out...
I need to know the values for following components:

C15
R8

and there is an empty hole on the circuit board just above the letters „PC4“.(see picture).

Is that ok or is there someting missing?

Thank you for your help.

Cheers, MW110.
