Re: vox ac
You wont get an ac30 ish tone out of that marshall no matter what pedal you use. If you are after something low gain and rich sounding, you can definitely get it (kinda like that cube tone but better) and you will be sure to get a cool sound, just don't get too hung up on replicating an AC30. No matter what the advertising says on this pedal or that pedal, you will always sound like you are playing thru a marshall, but via some kind of overdrive pedal. So try a few pedals until you are happy with what you are hearing. Don't overlook the tried and true fulltone fulldrive for a sweet singing midrange tone with plenty of tweakability and the extra boost for when you play high on the fretboard. I reckon one of those will get you 90% of the way there if you run thru your clean channel.
