Hi, 

I'm having some problems with my Marshall MG15MSZW Zakk Wylde Mini Stack and would like to know where I can find the wiring schematic so that I can go through it to locate the problematic electronic component(s)? 

I have not found any local service centers that possess this information so they're no help and can't fix it.  

Any help would be greatly appreciated. 

Thank you, 

Mark
