A balanced, regular guy (6)
I believe the answer is:
evened
'a balanced' is the definition.
(I've seen this in another clue)
'regular guy' is the wordplay.
'regular' becomes 'even' (synonyms).
'guy' becomes 'Ed' (short for Edward).
'even'+'ed'='EVENED'
(Other definitions for evened that I've seen before include "Made level" , "Made smooth and regular" , "Made smooth or equalised" , "Levelled" .)
