Sound grooves and round hammer strikes in a simple circular pattern on the top surface of ZBT cymbals magnify the basic sound of the distinctive ZBT alloy. Includes 18" crash ride and a pair of 13" hi-hats. ZBT Series Hi-Hats produce a sharp and focused sound with an excellent, bright chick sound. The ZBT crash ride produces a cutting ride sound with good crash qualities.The bright, intense, high-pitched sound of the ZBT series cymbals cuts through the mix of other instruments. The sheet origin and lathing techniques create high-volume projection that speaks quickly and brightly when struck and decays rapidly. Since ZBT cymbals are pressed and lathed from sheets of uniform, high-quality bronze alloy, they are remarkably consistent. The highly polished, brilliant finish looks fresh. Superb all-purpose ride cymbal. Excellent, clean stick articulation with controlled overtones. ZBT-Plus cymbals take Zildjian Bronze Technology up a notch with advanced hammering and lathing, and enhanced sound for versatility, musicality, and professional performance.
