Those loooooong notes in the guitar solo of GYOW, how he manages to put so much into playing one string only
Not unlike Neil Young, now you mention him! I'm a Neil Young fan too.
Also a lot of rifs that I just wouldn't know how to describe, but I keep finding the same fingerpositions for certain melodies. Two solos on the white album (Sugar Daddy & Say You Love Me), they're really just a variation on the same positions, the same key...
Also I notice he incorporates a lot of bass-riffs into his playing, I don't know if other guitarists do that. It's the fingerpicking style, but in an electric guitar riff it's unusual (f.e. opening-riff from live version of The Chain)
I'll leave it to the other guitarists here to verify if all this makes any sense
