Cat on brass perhaps making bull fiddle (10)

I believe the answer is:

contrabass

'bull fiddle' is the definition.
(bull fiddle can informally mean a double bass)

'cat on brass perhaps' is the wordplay.
'perhaps' indicates an anagram.
'cat'+'on'+'brass'='catonbrass'
'catonbrass' anagrammed gives 'CONTRABASS'.

'making' acts as a link.

(Another definition for contrabass that I've seen is " big fiddle".)

I've seen this clue in The Independent.
