What I mean by this is a full tube preamp and full tube power section. I will be upgrading my current set up soon to a better amp and cab to get more power and a bigger/better sound. A friend of mine plays through an Ampeg SVT-CL and I know that this is one of the best amps out there. But he pretty much told me that full tube amps are the only way to go. I know that I have to try them myself to see how they go with my sound but sometimes it's as if people think Ampeg is the only way to go and that amps that aren't full tube just plain suck. Maybe I just haven't owned one yet. What are your opinions?
