Jimmy Page - way ahead of his time...
Hendrix - again.. way ahead of this time...
Angus Young - the way he moves & rock the stage!
Steve Vai - priceless....
Malmstein - speechless... does he have more than 5 fingers?
Rythm..
James Hertfield - his pressence on stage... WOOW!
Dan Donegan, Tony Rombola, Glenn Drennen, John Connolly, Wes Borland, Brian 'Head' Welch, Gary Lightbody (not really his playing, but his songwriting and his riffs).
there are so many!! but most of the above indeed... if i have to remember just a few that really influenced the way i play: joe satriani, nuno bettencourt, steve lukather...
So far the biggest influence on my electric guitar playing would be none other than John Petrucci... As for acoustic guitar, I honestly don't know who influenced me. Haha. I suppose it's got to be a lot of those CCM singer-guitarists like Steven Curtis Chapman, Chris Tomlin, etc. They can be considered my favourites, too.
