Two comments (I missed this earlier).
One, That's nice, but King is the guy who Stevie Ray Vaughan based his entire style upon, not Collins.
Two, 'whom' should be used as the object of a prepositional phrase and not as a subject or a noun - 'of whom,' 'to whom," not "do you know whom?"
/grammar nazi.
Congrats on the grammar and your rhetorical point (although I think is it hardly sustainable that SRV was not influenced by Hendrix, you're the first person I think who has ever claimed that), but you're still completely missing the point. SRV based his style on guitarists slightly older than he was, about one generation or less (hope that's grammatically correct). King's career was essentially '60s after debuting in the 1950s, a few short years before Hendrix. SRV started off big-time in 1983, after a mid-1970s debut. So about a 20 year difference.
Most guitarists now copy (not base) their styles on guitarists two, three, four times further removed in time, and the degree of difference between a modern guitarist and their influences and SRV or Hendrix and their influences is much, much smaller. The only seriously influential guitarist of the last twenty years I think is Cobain, and he's mostly known as an anti-guitarist. And he broke nearly twenty years ago!
Do you reject the hypothesis that innovation in modern blues, rock, and even jazz music has ground to a halt? Where is new ground being broken? How can it possibly occur given the attitudes of modern guitarists?
I mean, again, Nirvana. Twenty years ago. I don't care what you think about Nirvana, they were massively influential. Nirvana to 2010, basically nothing new. Metal gets more metal-y, but in ways that were entirely predictable in 1990. Blues guitarists continue rehashing the same tones and same licks ad nauseum. Jazz guitarists still act like it's 1949. Mainstream rock bands are more interested in their mug shots.
Twenty years before Nirvana was 1970. Quite a lot a change from 1970 to 1990, but still much less than 1950 to 1970, wouldn't you say?
At the rate we are going, absolutely nothing will change by 2030. Enjoy the worst two decades of music in rock history, you thought the last decade was bad, you ain't heard nothing yet.
Actually you have. You've heard everything. There is nothing else.
Back to OP. PA gear is changing. The way live sound is done is changing, and the way concerts are performed is changing. Clinging to methods of the past by slavish devotion to vintage gear or modeling are both paths to artistic failure.
