I find for the classic hard rock crunch, Van Halen Brown Sound, , Led Zep type crunch, the dirty channel on
my RT-2100 Tube Works combo, similar to your head on the pre-amp side, give me all I need and more.......
If I want the Joe Satriani, smooth silky sound, then, no, it's wont deliver. When these amps were made, that sound was just beginning to appear on records at the time.....same for today's Heavy Metal sound....these amps were made before that sound became popular, thus, the line won't get you that sound on it's own.
The MV-962's mentioned above are strictly power amps, 100% pure clean......absolutely great for the current, modern processors with Amp Modeling.
They say you can't get the tube sound with solid state... I say B.S.

With my MV-962, and
my Boss GT-6, I've had locally known tube nazi players ask me what I'm using.......it's how you set stuff up.......get it right, it's amazing, if not, it can sound very sterile......
