The Paiste 900 Series is really about evolution. These heavy weight cymbals are a result of the evolution of the CuSn8 alloy, the same alloy used to make the classic 2002 and Rude cymbals, with the exacting Swiss lathing and hammering techniques Paiste is known for. This pack is the classic pack with even sizes, and it consists of 14" 900 Heavy Hi-Hats, 18" 900 Heavy Crash, 20" 900 Heavy Ride, plus a FREE 16" 900 Heavy Crash (a $240 value)! At Drum Center of Portsmouth, we are all about value, and this Paiste 900 box set certainly delivers that and more!
