Device is Fender guitar, a fine example (9)
I believe the answer is:
stratagem
'device' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for stratagem that I've seen before include "Scheme to outwit an opponent" , "Ploy - start game (anag)" , "could be a trick" , "Ruse" , "Device" .)
