The term 'BASSOONISTS' BUYS' is a crossword solution that refers to the reeds used by bassoonists. Bassoonists use double reeds, which are made from two pieces of cane that are tied together and then cut to the desired shape. The reeds are then soaked in water and scraped down to the desired thickness. Bassoonists must purchase new reeds regularly as they wear out quickly due to the nature of the instrument.
