Zildjian S14MB S Mastersound Hi Hat Bottom - 14"Mastersound HiHats feature a hammered outer edge bottom cymbal, which not only prevents air lock, but creates a lively, fast chick sound and an overall balanced tonal presence. Choose 13 diameter for more control and articulation, or 14 diameter for a versatile range of frequencies and full bodied response. An exhaustive two year research and design project by the Zildjian Sound Lab results in a modern cymbal voice from the legendary Zildjian Company.
