I believe the answer is:

beaten-up

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

'battered' is the definition.
(synonyms)

'starter of bass fully consumed' is the wordplay.
'starter of' says to take the initial letters.
'fully consumed' becomes 'eatenup' (I've seen this in another clue. I am not sure about the 'fully' bit.).
The first letter of 'bass' is 'b'.
'b'+'eatenup'='BEATEN-UP'

Can you help me to learn more?

I've seen this clue in The Telegraph.
