The KMB411 and KMB412 marching baritones were crafted with the help of the World Champion Blue Devils Drum and Bugle Corps. With a rich tenor voice and enhanced ergonomics, the KMB411 and 412 horns are lightweight and well-balanced. The .560" bore, and 10" bell make for a broad and powerful baritone ready for the demands of the marching field. They are available for small shank mouthpieces (KMB411) and large shank (KMB412).
