I recommend getting rid of the ground buss connected to the pots as it created a ground loop. also, the grounding of the power board is no good. try larry grounding and have way less noise and ghosting

Hi, for that marshall sounds I'd recommend CFs, esp on the plates. CC 100Ks undermine that open ac/dc sound. also, I prefer to use some ceramic caps, not just silver micas in my 45/100. try a 270pf and see if you like it - some of the originals used 270 rather than 250pf, at least this is what one of the schematics shows
