A good rock guitarist list KiwiM. I said here before Ritchie Blackmore used one the readers best guitarist vote for Sounds, (Heavy metal newspaper), magazine for about 5 years on the trot during the 80's.
Guitarists I like include, George Harrison, Dick Dale, Ron Ashton, Dave Davies, Bob Mould, Graham Coxon, Johnny Ramone, J Masics, Tony Iommi, Johnny Marr, Mick Ronson, Alex Lifeson, (always underrated probably my fav), Lou Reed, (underrated), John Williams on Kate Bush's The Morning Fog - sweetest guitar. God there are gazillions, you could go on forever and I'm fairly clueless about the technical aspects of guitar playing I only learned a little.
