I believe the answer is:

bombard

I'm a little stuck... Click here to teach me more about this clue!

This could be a double definition.

'an old bassoon' is the first definition.
'bombard' can be an answer for 'bassoon' (thesaurus). I am not certain of the 'an old' bit.

'shell' is the second definition.
(I know that shell is a is a more specific form of the action bombard)

'in' acts as a link.

Can you help me to learn more?

(Other definitions for bombard that I've seen before include "Attack with missiles" , "Attack persistently" , "not working? Keep hitting" , "Batter heavily and persistently" , "Organ stop" .)
