Designed for drummers that are looking for bright, explosive and cutting sound. The Project 391 cymbals will be offered in 2014 for a limited time only. Project 391 is Zildjian’s first publicly available product crafted from B15 alloy, known for its consistency and cutting sound. A two step hand-lathing process imparts a unique surface finish that is both visually and sonically pleasing. Exiting, because B15 is an alloy that the company didn’t work with before.
