Killer ZHT sounds for hard hitting styles. The Zildjian ZHT Rock 4 Pack is a factory matched set of 14" Rock Hi-hats, 16" Rock Crash, and 20" Rock Ride. The 14" hi-hats have a heavy, focused sound with aggressive attack, projection, and a pronounced cutting chick sound. The 20" Ride is a heavy, high-pitched model with maximum stick definition and a powerful bell. The 16" crash is high pitched with enhanced attack and volume. For their ZHT series Zildjian chose Ultimate Sheet Bronze, an alloy with a higher tin content for enhanced low- and mid-frequencies. This extraordinarily musical metal, combined with ultra-modern manufacturing techniques and extensive hammering, has resulted in cymbals of extraordinary musicality and value.
