The great Stradivarius swindle? (6)

I believe the answer is:
fiddle
This clue might be a double definition.
'the great stradivarius' is the first definition.
'fiddle' can be an answer for 'stradivarius' (thesaurus). I'm unsure of the 'the great' bit.
'swindle?' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for fiddle that I've seen before include "Scam - musical instrument" , "violin > scam" , "for which one takes a bow" , "Cheat on (e.g. expenses)" , "Fraudulent instrument?" .)
