Orange pip damaged musical instrument (4,5)
I believe the answer is:
pipe organ
'musical instrument' is the definition.
(I know that pipe organ is a type of keyboard instrument)
'orange pip damaged' is the wordplay.
'damaged' is an anagram indicator.
'orange'+'pip'='orangepip'
'orangepip' is an anagram of 'PIPE-ORGAN'.
(Other definitions for pipe organ that I've seen before include "Traditional church instrument" , "Musical instrument" .)
