Guitar master Paul (3)
I believe the answer is:
les
'guitar master paul' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for les that I've seen before include "- Dawson, Br. comedian" , "-- Dawson (late comedian)" , "-- Dawson, English comic" , "-- Miserables, musical" , "French definite article" .)
