Zildjian S-series cymbals are made from B12 bronze – 88% copper and 12% tin – to provide a balanced range of lows, mids, and highs for brilliant shimmer and signature Zildjian smokiness. B12 bronze lands somewhere between Zildjian’s budget B8 bronze and premium B20 bronze for good balance, projection, shimmer, and wash for the price. Zildjian S cymbals feature lathed tops and bottoms for an open sound with plenty of sustain, extensive machine hammering for an even tone that cuts through a mix, and a brilliant finish that looks great under stage lights.
