The S.E. Shires Custom BII5YM bass trombone is a versatile instrument with a clear, pure sound and the consistency, playability and projections that has made S.E. Shires trombones the favorites of professionals the world over. The 5YM bell is a brand-new offering from Shires; patterned after a Bach Corporation 50 bell, this is the first one-piece bass trombone bell Shires has designed and it offers a full sound with a lot of core and a high level of stability at upper dynamics. The axial-flow valves feel very broad and even-especially when both valves are engaged-and allow for a truly open low register.
