Béla Fleck's instrument (5)
I believe the answer is:
banjo
'bela fleck's instrument' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for banjo that I've seen before include "Bluegrass instrument?" , "Stringed instrument with circular body" , "Stringed instrument beloved of old minstrel shows" , "No jab (anag.)" , "Five-stringed musical instrument" .)
