The A Series Zildjian is the world's most popular and versatile cymbal. Created from cast bronze alloy of 80% copper, 20% tin, and traces of silver, it is symmetrically machine hammered and lathed with a traditional wide groove. The result is an exuberant cymbal that bursts with a classic voice that is pure, bright, and expressive. The Quick Beats have an especially fast response with 4 holes in the bottom that allow quick air release.
