The KT-3ZC12 is a 3-zone 12 inch. crash cymbal that is designed to work with the KAT kt4 drum module. By having 3-zones on the crash cymbal this gives you 3 individual sounds on one cymbal - bell, bow, and edge, tripling your sound options when playing. The durable gray rubber gives a natural stick rebound while keeping the ambient noise to a minimum. Also included is a cymbal stem adapter that will attach to your cymbal arm stem and a 1/4 inch. 8ft connection cable.ÿ
