Instruments adapted to submarine (11)

I believe the answer is:

tambourines

'instruments' is the definition.
(tambourine is a kind of instrument)

'adapted to submarine' is the wordplay.
'adapted' is an anagram indicator.
'to'+'submarine'='tosubmarine'
'tosubmarine' is an anagram of 'TAMBOURINES'.

I've seen this clue in the Sydney Morning Herald.
