Carlos Santana
John McLaughlin
Jerry Garcia
I agree about Garcia. Interesting anecdote: He did the pedal steel guitar on Crosby, Stills, Nash & Young’s “Teach Your Children”, even though he didn’t know how to play the instrument. He told Lon Goddard of the British music newspaper Record Mirror in an interview, that he recorded a series of pieces on the steel guitar and spliced them together in the studio to create the backing and solo.
