We've listened to you, our customers, and today we are proud to announce the change to DUAL SIZE mutes! More adaptable, more versatile. The same great performance, the same great solution. Now all cymbomute mutes will fit both even and odd sizes of cymbal. So if you've got 14,16,19,21 - then, good news, the money saving set of four is now all you'll need! Another step in the evolution here at cymbomute.com Thanks! Hugh.
