its hard to name just 1 - my list of influences from the 1960-90s is a list close to 50 names. players that i grew up covering n learning from their songs, not just listening to them.
there are many versatile players who can change their approach like rubber band.
1 guy who played blues, jazz standards, rock n shred guitar in my face, was Andy Timmons during his clinic. Steve Lukhather is another name that comes to mind. Arjen Lucassen is another wizard, check out the new Ayreon LP. there r more..........
these guys r all studio sessionist - multi-styled playing gets u more calls to session work.
