Yeah, I know many do. No worries about that, from me, but one thing you can do with a modern, SS amp that you would not ever try with a vintage tuber is to DROP IT DOWN A FLIGHT OF STAIRS AND PLAY THE GIG THE SAME NIGHT WITHOUT A TRIP TO THE AMP SHOP. Of course, no sane person does that on purpose, but it happens, fairly often. And, using my favorite touring SS amp-
the Peavey Bandit 112- as an example, even if it DID go "poof!" at the bottom of the stairs, you can easily find another one, for around $100-200, in the town's craigslist, or a pawn shop, or just buy a new one at the local music store (most EVERYBODY carries Peavey) and be back in business with an amp that you are familiar with- in a matter of just a couple of hours. Try doing THAT with almost ANY tube amp- it will take you that long just to find someone to work on it.
Now, please don't think I am getting in your face about this- I am not. No rancor, on my end. And, yeah, I, too, get a charge outta playing out thru my SF Deluxe Reverb. All I'm sayin' is that no one can really hear the difference, in a live setting. No one even GOES to a rock concert for the subtleties of tone- they go for the "event." Some folks do listen to recordings for that, and that's why there are tube amps that are legendary studio amps- but it just does not happen, live.
Good enough is best.
And really, the ONLY reason any of us haul expensive, pricy, touchy, fragile, heavy, vintage or WHATEVER gear around to jams, gigs, and such, is for our OWN enjoyment and/or motivation. (Well, there is another reason- because the audience wants to SEE silly things like huge Marshall stacks and such.) We do it because we believe it makes us play and sound better- and it does, probably only because we
believe. We take pride in our gear and our performance. It's a personal, psychological thing. And really, there's nothing wrong with that.
