Maybe it is a generation thing. When I was young we often lit fires in the woods and we used a lighter on concerts. Our kids - or rather the kids if my kids - might be never experiencing anything but the leds of smartphones in concerts. Same but different.
So going the tube alley is a feeling we are used to due to our experiences in certain ages and the given possibilities.
Saying that, if you are growing with technology you might go for the comfort and ease provided and that is not tubes. Current technology provides us all the sounds in one box. And if it is made right we are no longer able to distinguish but in the look of the gear.
For me it still took a while getting used to a mic‘ed guitar amp but after „overcoming“ that I was really impressed by the KPAs abilities. Still happy since three years.
Seriously now,guitar players have been to long mostly "rehearsal audio" type of musicians.As rock musicians in general but in opposite to drummers,bass players and ofcourse vocalists electric guitar only and exclusively sounded good under inhumanely loud conditions.Ofcourse this is the same with bass players and drummers but we guitar players always had this "cranked" thing which most bass players I ever met did not have.Only a few.
So the volume knob thing is really a serious issue.One channel,many,many sounds..this was the classical tube thing.Together with one,two "essential" pedals.
But today even plug ins..have become good with the volume knob.It is only a matter of time until this discussion ends once for all.
