Designed with System of a Down's drummer, the 5A shaft has a barrel tip for a beefy, easy-play design. Shaped for comfort, balance, durability, and speed. 16" long; .585" diameter. Speaking of his design, Delmoyan says, "I designed the tip so it has more bounce and more speed. These factors will give you more powerful techniques and graceful rhythms." Audition a pair. We think you'll be impressed.
