Change plug perfectly (6)

Ross

I believe the answer is:

adjust

'change' is the definition.
(to adjust is to change)

'plug perfectly' is the wordplay.
'plug' becomes 'ad' (as in plugging a product).
'perfectly' becomes 'just' (as in 'just so').
'ad'+'just'='ADJUST'

(Other definitions for adjust that I've seen before include "Modify, adapt" , "Change slightly to fit" , "Calibrate or regulate" , "Modify - tweak" , "Fine-tune" .)

I've seen this clue in The Telegraph.
