Technique can be taught though. My fingers are the same now as when I started playing, but I know how to do different things.
		
		
	 
If you know how to do different things with them, then I'd say that your fingers aren't at all the same as they were when you started playing.  Your fingers are more accurate, they're stronger, and your mind knows how to control them better to translate the music in your head into the sounds you hear.  That's a huge difference!
	
		
	
	
		
		
			If I had brief clips of a few different hair metal guitarists playing JB-loaded super Strats through hot-rodded Marshalls, could you tell which guitarist was which? Probably not, but you’d know it was a JB through a Marshall each time. Ditto with nu-metal players with PRS or Ibanez guitars through Mesa Recto amps, or metalcore guys playing EMG-equipped guitars through TS-boosted Peavy 5150s/ 6505s. Different guys playing similar equipment will sound similar.
		
		
	 
Again, I think that this depends an awful lot on 
what is being played.  Nu-metal/metalcore?  Yeah . . . with the gain up that high, you either get a not to sound or not to.  Nuance and subtlety of touch aren't really demonstrated in the genre.  There's not much personal in the playing . . . just the attack of the instrument.
Bizarrely, I think I agree with Ted Nugent on the different hair metal guitarists playing the same rigs' question though:
"I was a bad motherfucker in 1978, and I heard all about this Eddie Van Halen guy.  And they're out there doing a soundcheck - we want them to have a good checking of their sound, and I'm listening to the guys and, of course, they're just world-class musicians, Alex [Van Halen, drums] and Michael [Anthony, bass] and Eddie and David [Lee Roth, vocals], and they're out there with this brand new thing called Van Halen, and it was a monster.  And I'm listening to this screamy high end - he [Eddie] had a little bit of phaser going on, he had some kind of electronic warfare going through his amplifier that he completely tore apart and rebuilt - he's just an electronic maniac. And I listen, and I'm going, 'God damn, what kind of an instrument and an amp does that son of a bitch use?!'
I went out to watch those guys and they went to talk about the tour, the music, the inspirations, and the tone, and he goes, 'How did you get that Byrdland to sound like that?'  And I saw my Byrdland right there, and I said, 'Well, here, plug this son of a bitch in, we'll keep it in my Fender amps.' And of course, my Byrdland feeds into that low volume, the Byrdland wants to eat your phase.
So, Eddie's playing, but once he got out of the feedback - there's a feedback that will literally eat the notes you're trying to play. The feedback is so strong, you could go for a scale in the key of B, but the feedback is resonating in the key of D and there's not a damn thing you can do about it.  So he repositioned himself, he started pulling these mystical licks, and it sounded just like him, but out of my rig.  And I grabbed his Strat - his mutilated, bastardized Strat - and I started playing 'Dog Eat Dog' or 'Cat Scratch [Fever]' or something, and it sounded just like me.
If music is anything, it's not only the universal language, not just the universal communication for people anywhere in the world at any time, but it's also a personal execution of the musician's sonic vision.
And when you practice your balls off, when you dedicate yourself to be the very best you can be, which describes every musician that you and I love...
It's you, not even the Fenders or the Gibsons. It's you coming through your musical vision and attack of the instrument. You could have an amp and a guitar, don't change any of the settings and put 10 of your favorite guitar players on that set and it will sound just like each individual." -
