The S.E. Shires Custom BII 7GM bass trombone is a versatile instrument with a clear, pure sound and the consistency, playability, and projection that has made S.E. Shires trombones the favorites of professionals the world over. The unique S.E. Shires 7GM bell combines the quick response and color of a one-piece bell with the centered feel and expansive tone of a two-piece bell. The BII bell taper in gold brass produces a broad, rich sound that is very balanced and flexible throughout the range of dynamics. The patented S.E. Shires Tru-BoreTM valve blends a broad, rich sound with an efficient, centered feel. Recognized as a leader in brass instrument design and innovation, S.E.
