Combs over regularly -- it gets blown in the wind (4)
I believe the answer is:
oboe
'it gets blown in the wind' is the definition.
(instrument in the wind section)
'combs over regularly' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'combs'+'over'='combsover'
The alternating letters of 'combsover' are 'OBOE'.
(Other definitions for oboe that I've seen before include "Musical instrument" , "Orchestral instrument" , "it's blown" , "Producer of notes" , "Double-reed woodwind" .)
