Crossword Genius

Abhor not having instrument (4)

Ross

I believe the answer is:

horn

'instrument' is the definition.
(horn is a kind of instrument)

'abhor not having' is the wordplay.
'having' indicates a hidden word.
'HORN' can be found hidden inside 'abhor not'.

(Other definitions for horn that I've seen before include "Instrument - rhino's appendage" , "Warning device on a vehicle" , "Head growth; cornucopia" , "Head appendage; warning instrument" , "Wind instrument - cape" .)

I've seen this clue in The Mirror.
