Hi I guess this thread is dead since no one has written in for at least a year but i give i a try.

I have a Marshall 12 Micro stack and I thinking about changing speakers in it and also add the capacitor mod in it. I also got an idea to put a clipping stage in it by adding two diodes and a switch to handle it with. Is it possible to add it after the R8 resistor? See attatched Pictures of the pre stage and a clipping stage. I know that it is clipping stages in other Marshall SS amps
