Metallica are kings of the guitar riff.....just listen to the Black album
But yes I agree with most of you.
There are soooooo many GREAT guitar legends out there.
Vai, Satriani, Hendrix, Slash, Hammett the list goes on and on and on and on.............
Some of the old blues guys kick ass all over the place.
You ask Slash who his biggest influence is ...........Brian May
Ask Brian his...........................................................Jimi Hendrix
Ask Jimi....................................................................Elmore James.
These old guys can make an acoustic do what young guys do with a little more electric.
I don't have a particulat fave. It depends on my mood.
It may be Gilmour, Moore, Vai, BB King, Slash,
Yngwie Malmstein is another.
I just lie back and drool.
