After getting down the licks through my archtop and stuff, all I sounded like was Elmo-trying-to-sound-like-B.B.
I once got a Ibanez Tube Screamer and gauged up my strings on my Strat to get a SRV sound along with an SRV book with the same results.
My point is, my heart and fingers will never sound like those guys, but I'll sound like a kewl Elmo with some good chops and licks!
