The B4 was developed on the basis of the Bach Mount Vernon trumpet. Fundamental to the rich sound is a standard bell with a normal-weight valve cluster. Unlike the original instrument, the B4 is distinguished by its improved slotting and lighter intonation. This is a reliable all-rounder for all kinds of music-making.
