Sporting features like an ultra-thin flanged edge for added trashiness in the response, a medium-thin weight through the bow for added sustain, and a full 20 rivets drilled into the perimeter of the cymbal for a big, smoky sizzle, the Zildjian A 22" Swish Knocker is one of the largest and most unique effects on the market. Exploding with bright china-like projection that benefits from an added sustain thanks to the size and rivets, the Swish Knocker is an automatic signature sound on any setup.
