Instruments from India employed by idols (6)
I believe the answer is:
sitars
'instruments' is the definition.
(sitar is a kind of instrument)
'india employed by idols' is the wordplay.
'india' becomes 'i' (phonetic alphabet: alpha, bravo, charlie etc.).
'employed by' means one lot of letters goes inside another.
'idols' becomes 'stars'.
'i' placed inside 'stars' is 'SITARS'.
'from' is the link.
(Other definitions for sitars that I've seen before include "Music makers" , "Indian stringed instruments" , "Instruments from India" .)
