The Model 1500-A features a one piece hand hammered bronze bell from Kanstul's no. 7 mandrel, and is carefully balanced with a no. 25 mouthpipe and medium large bore.

The heavy mouthpiece receiver, weighted bell bow and weighted bottom caps offer increased projection and stability. This model includes two tuning slides: the weighted slide helps give the player more secure slotting, while the dual bore un-weighted slide helps the horn really sing in the upper register. A Zig Kanstul Signature Model.

Virginia trumpet players Rob DeDominick, Larry Hart and Roy Muth together have backed up The Temptations, the O'jays, Frankie Valli, Fabian, Frankie Avalon, Bobby Rydell, Johnny Mathis and more.
