Did I miss Eric Clapton here?
What about Jerry Reed. Leona Boyd.
And, since someone opened this up to "resonophonic" instruments, I must suggest two of America's greatest musicians (IMO): Bela Fleck and Edgar Meyer.
Bela Fleck is to the banjo what Lionel Hampton was to the vibraharp: the transcental performer.
Edgar Meyer plays several instruments, but the string bass is his specialty. I know professional classical musicians who consider it to be ridiculously impossible to play Sarasate's "Ziguerneweisen" (no spell check, sorry) on a string bass. Meyer recorded it. They listened. Shook their heads, rolled their eyes, still said it was impossible.
Similarly, check Bela's recording of classical music on his "Perpetual Motion" album. Your ears will never be the same.
