right on man u hit it dead on i dont think there are any other guitar players that match the skill of jimmy page im a led zzeppelin freak i have everyone of their albums i no all there songs and i myself play guitar and can pretty much play all their songs but next to jimmy page is deffinetly Hendrix i mean he is just so badass...... his skills are amazing and i mean he freakin cut his forhead drenched his head band in acid and put it on and still rocks the shit out of all his songs= beast mode

I believe that many people place too much emphasis on fast fingers alone and far to little on how different players influenced rock music and others who followed in their paths in later years. Some of the most influential guitarists of all time seldom have their names brought up in discussions like this but if you read or hear what is said by professional musicians those seldom heard names often times top the lists of who was/is among the very best.

My influences are
Carlos Santana
Jimmy Page
Jimmi hendrix
stevie ray vaughn
muddy waters
guitarist from pink floyd

That is a fairly respectable group to be influenced by. All of them are in Rolling Stones Top 100 guitarists of all time list.
　
David Gilmour was Pink Floyd’s guitarist and performed vocals too. He was voted No. 1 in Fender's Greatest Players poll in the February 2006 and that ain’t bad.
