Tuner ordered by a man out of gear (7)
I believe the answer is:
neutral
'gear' is the definition.
(I've seen this before)
'tuner ordered by a man' is the wordplay.
'ordered' indicates anagramming the letters.
'by' says to put letters next to each other.
'a man' becomes 'al' (man's name).
'tuner' is an anagram of 'neutr'.
'neutr'+'al'='NEUTRAL'
'out of' acts as a link.
(Other definitions for neutral that I've seen before include "Impartial; beige" , "Impartial; colourless" , "Not allied to either side" , "Not taking sides in a war" , "not getting involved?" .)
