From the manufacturer:
New in Meinl’s Byzance Extra Dry Series is the 21” Transition Ride, Mike Johnston’s signature cymbal.
Both Mike’s and Meinl’s goal was to create a cymbal that can effortlessly transition from articulate sticking to a wide open and tonally fuller crash-ride function (and back) while never losing the stick definition. The result is a multi-puprose ride cymbal with a versatile sound.
