Also note.
If you do choose Tube over SS, keep in mind that most musicians modify the hell out of their tube amps to get certain features / sound not built into stock units.
Swapped out resistors, added gain circuits, and trick pots are common in pretty much every heavily gigged musicians rig. So don't choose purely based on "Well Stevie played fender Tube heads"
But like anything you have to give it the "ear test" in a quiet place where you can really feel it out through it's paces.
Anyone who wants to sell you an amplifer, tube or SS is going to let you take a dry run at it. Be sure to also take along your favorite pedal or two, and a couple cables so you can try different combinations or effects, clean etc.
The real question is that $450 middle of the road Tube Combo better than the $300 Line VI or Marshall or (insert brand name SS amp here.)....That will be up to you.
But I really looked at it like this when I bought my tube combo. Literally every piece of music I am in love with, was recorded in a studio, with a vintage tube amplifier and almost all of it, to magnetic tape, and THEN digitized.
So as far as being true to the original signal, keep it analog. Keep it tube.
And that's the way the cookie crumbles....
