You know when a guitarist is really good, when you can tell who it is from the first few notes, despite having never heard a particular song before.
I get what you’re saying, but as others have said, that description also covers guitarists of limited talent and imagination, i.e. those always basically playing the same thing, or variations thereof.
Fwiw, I know I’m far from alone among guitarists in really not rating t’edge as a guitar player. Not too say him and his band haven’t accomplished great things as sonic constructionists, but as a player of the instrument? Not seeing (hearing) it.
As for instantly identifiable, imo both due to tone and playing style, and certainly not because everything he does sounds the same, I’m surprised Brian May hasn’t been mentioned yet.
