Thanks for that info, Ken.

I guess this is the way things will be for touring musos; modelled amps, in ear monitors etc. A potential downside could be an overall sound homogenisation, as happened in the 80's and 90's with the proliferation of SSL desks.
I had the pleasure of hearing the opposite of that scenario last night at Glasgow's own Grand Old Opry; a decent vocal pa, with wedges and a touch of kick drum in it, and that beefy backline of Peavey, Fender and Peavey

The band was Cimarron with Granpaw Gamble on the steel, sweet

Old Skool without a doubt but when it's done right you canny whack it.
As for a question for Mr. Johnson; as he is now a player, up there on the mountain top, that is a/thee source of inspiration for so many: was there one player, above all, who fired him up, as a young picker? Total fanboy question
