Zildjian A Swish Knocker 22": the jazz-rock special-effects cymbal

Zildjian's 22" A Swish Knocker (SKU A0315) is a special-effects cymbal built at the intersection of a china and a ride: 20 rivets set into the bow add a sustained sizzle, while the cymbal's profile and weight let a drummer play continuous stick patterns across it rather than just crashing it once. Zildjian's own product copy calls the redesign "a smoother and sweeter knock" than the vintage original, with a slightly higher profile and less curved cup.

The design lineage runs back to Mel Lewis, the big-band drummer best known for his decades leading the Vanguard Jazz Orchestra's Monday nights at New York's Village Vanguard. The swish-with-rivets sound became part of his signature kit, and Zildjian's current A Swish Knocker keeps that idea in continuous production as a standard catalog item.

It's also, by name, Charlie Watts's cymbal. In a 2012 interview with DRUM! Magazine, Watts described his setup directly: "I have the same hi-hat and ride cymbal with both, and I have a special cymbal, a Zildjian Mel Lewis Swish Knocker, and a thin crash that Zildjian gave me. My ride is an 18-inch UFiP flat ride, and I've never found one as good as it." The Swish Knocker wasn't his main ride voice, that was UFiP, but it's the one Zildjian product he named specifically as his own.

Zildjian's own description promises "great stick definition for funky ride beats with roaring overtones," and that's the core of the design: a china's trashy, complex overtone spread, but with enough definition from the 20 rivets and the cymbal's weight that a stick pattern still reads clearly on top. It's louder and busier than a standard crash or ride; that's the point of a special-effects cymbal in this category.

Jazz and big-band drummers who want a textured, riveted cymbal in the swish/china family for accents and extended patterns. Rock drummers with a jazz background (Watts is the documented example) who want one distinctive, sizzly voice mixed into an otherwise conventional kit. Drummers building a Vanguard Jazz Orchestra-style big-band setup who want the Mel Lewis lineage specifically.

Drummers looking for a primary ride or crash. This is a special-effects cymbal, not a workhorse; most kits run one alongside standard rides and crashes, not instead of them. Quiet acoustic or low-volume settings also aren't a natural fit: the rivet sizzle and china-adjacent trash are loud and busy by design, the opposite of subtle.

A distinctive texture cymbal with real lineage: built on the Mel Lewis big-band sound, still in Zildjian's catalog today, and namechecked directly by Charlie Watts as the one Zildjian cymbal he reached for. Not a first cymbal purchase, but a strong pick for a drummer who already has a ride and crash covered and wants one more voice with personality.
