But the surviving amps from the '70's are getting to be pretty thrashed - if you can even find one. Why doesn't some enterprising young amp builder put out an amp that sounds like an old VT-40 or V4? I know the unusual tubes Ampeg used were responsible for a good part of their tone but couldn't someone put a similar sounding circuit together with 6L6's, EF86's, etc.? (Please?? ) The old Ampegs had/have such a great tone but I don't know of any amp builder that's building such a beast these days. I'm looking at buying an old AC-12 right now. It sounds very good but it looks like it spent a few years under a pile at the local dump. The chassis is barely attached and it looks like someone took a chainsaw to the left side of the cab.
