Rushes to get some instruments (5)
I believe the answer is:
reeds
This clue is a double definition.
'rushes' is the first definition.
(I've seen this in another clue)
'some instruments' is the second definition.
(reed is a kind of instrument)
'to get' is the link.
(Other definitions for reeds that I've seen before include "Plants providing thatching material" , "Thatching stalks" , "Marsh plants with tall straight stems" , "Water plants" , "Tall water grasses on lake shore" .)
