Stick held by conductor oddly (3)
I believe the answer is:
rod
'stick' is the definition.
(I've seen this before)
'held by conductor oddly' is the wordplay.
'held by' indicates a hidden word.
'ROD' can be found hidden inside 'conductor oddly'.
(Other definitions for rod that I've seen before include "Baton, pole" , "See 13" , "Straight, slender stick" , "Stick - measure" , "The fly fisherman's stick" .)
