Current producer withdraws a good deal in style (6)
I believe the answer is:
dynamo
'current producer' is the definition.
'withdraws a good deal in style' is the wordplay.
'withdraws' says the letters should be written in reverse.
'a good deal' becomes 'many'.
'in' is an insertion indicator.
'style' becomes 'do' (both can refer to a hair style or hair do).
'many' reversed gives 'ynam'.
'ynam' going inside 'do' is 'DYNAMO'.
(Other definitions for dynamo that I've seen before include "Juice supplier" , "something electrifying" , "Small generator" , "energetic individual" , "Forceful person" .)
