Double-reed player (6)
I believe the answer is:
'double-reed player' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for oboist that I've seen before include "Do I boost the musician?" , "Instrumentalist" , "Musician who plays woodwind of treble pitch" , "Player of woodwind instrument of treble pitch" , "orchestra member" .)
