I have just come across a business that modifies existing guitar amp modules, (based on Randall MTS modules) which is interesting and neat (see here for an example of them in an interview with Billy Corgan). However, what I don't understand is how I would use one of these in my own rig. They are, but how would I hook them up? Could I use one to drive a speaker cabinet? Do they need to be in an enclosure? Basically, how would I use one of these modules?
