Ok...I apologise in advance for this, but you did ask....here we go, in no preferential order......(draws breath).......
Chet Atkins, James Burton, Stevie Ray Vaughan, Mark Knopfler, George Harrison, Dave Gilmor, Ritchie Blackmore, Brian May, Mike McReady, Jerry Cantrel, Chuck Berry, Eric Clapton, Jeff Beck, Joe Walsh, The three Kings - Albert, Freddy & BB, Buddy Guy, Elmore James, Roy Buchanan, Kirk Hammet, Tom Morello, Ben Harper, Noel Gallagher, Dave Navarro, Jimi Hendrix, Vernon Reid, 'Keef' Richards, Mick Taylor, Izzy Stradlin (great rythms!!), Hilel Slovak (check Uplift Mofo again, you'll see what I mean)
Plus I'd better show patriotism and include a few Aussies in, Tommy Emmanuel, Geoff Achison and Ross Hannaford (sound here, not ability).
But there is one and one alone who can still send shivers down my spine. James Patrick Page!!
Apols to the other 300 or 400 that I've left off, but that is surely enough for one post.
