Hi,
Over 10 years ago I bought some kits from Mammoth Electronics and life got in the way. My son is starting to play guitar and thought I might completed these pedal kits only i cannot find the schamtics online. Each kit says it came from GuitarPCB. On the PCBs they say
MRC V1

BMPOA V1 – Dons not work, Likely due to terrible soldering…

Hot Silicon 1.2

I can see newer versions of thesebut as I have the PCBs and the parts i wondered if anyone had access to these old schematics?.
