For reproducing sound of the best ever instrumentalist? (6,6)

I believe the answer is:

record player

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

'for reproducing sound of' is the definition.
I can't tell whether this defines the answer.

'best ever instrumentalist?' is the wordplay.
'best ever' becomes 'record' (similar in meaning. I am not sure about the 'ever' bit.).
'instrumentalist?' becomes 'player' (synonyms).
'record'+'player'='RECORD-PLAYER'

'the' acts as a link.

Can you help me to learn more?

(Another definition for record player that I've seen is " Spinner".)

I've seen this clue in The Irish Independent.
