Sabian's AAX FREQ design is an exclusive dual-lathing process that results in unique, intensely-cutting crashes that deliver quick bursts of hi-frequency tone, and fill the stage with big, open sound. Although most rock cymbals cut with focused high-pitched tone generated by the bell, the Freq Cymbals gets their boosted cut from the exclusive FREQ dual-lathing process. Once you hear these cymbals, you’ll want to get your FREQ on! What's Included: 14" Freq Hi-Hats 16" Freq Crash 18" Freq Crash (FREE!) 21" Freq Ride
