Zildjian 20" A Custom Projection RideBeautiful, loud, clear bell and clean articulate "ping" with just the right amount of shimmering undertones. Responding to requests for the heavier, louder volume needed in rock settings, the Zildjian Sound Lab created the Projection series. Developed with the assistance of Vinnie Colaiuta, A Customs are made using radical rotary hammering techniques, thin weights, and a striking, brilliant finish.
