Most shredders, Clapton, Jimmy Page, David Gilmour, BB King and most of all Carlos Santana (screws up every single he asked to play on).
I forgot santana. And clapton.
Also,
Mustaine
I'd say Hammet but he doesnt count because hes actually sucked since 1991
Chris Broderic is probably one of the most technically talented and versatile musicians alive, and his dedication to continually learning and improving, along with his humility, are an inspiration. His playing bores me $%&#ing senseless.
Muhammed Suicmez.
Malmsteen. Obvioulsy.
Frank zappa.
His progeny.
I dont know that hes supposed to be 'good' but john fruscantes "playing" does my head in (with a couple of songs as exceptions).
Zakk wylde.
Starting to feel like a bit of a naysaying tosser now (though that seems to be what the topic wants...) so some guitarists I do really really like. They may or may not be terribly 'technically acomplished', but I like their playing and tunes.
Karl sanders and dallas toler wade (nile)
Paul Ryan (Origin)
Rodrigo and gabriella (and = y)
Paco delucia
Paul kossoff.
James hetfield
Tony Iommi
Mike Sullivan (russian circles)
Aaron turner (but only in ISIS)
Pepper Keenan (Groovy Rifftastic)
Tommy Emmanuel
Mark Tremonti....yeah, I went there. He got good, and I like his style.
