Bass Trombone Valves

The Edwards B454 is an independent double bass axial flow valve system. The independent valves give players additional positions with which to work. The valves are pitched in F and Gb (combined to produce D) with open wrap design. Additional keys are available for the second valve upon request. With the open wrap design, the B454 has a very open feel. Valves are nickel plated and will not oxidize. These valves are very dependable and maintain the same sound on F, Gb/D, and Bb sides.

The B454-D is a dependent double bass axial flow valve system. The second valve (D) will only work when the thumb trigger (F) is depressed. There is a more open feel with the dependent configuration as the second valve does not interrupt the airflow on the open side of the trombone. With the open wrap design, the B454-D has a very open feel. Valves are nickel plated and will not oxidize. These valves are very dependable and maintain the same sound on F, D, and Bb sides.
