Because an airtight valve is essential to quick response and centered feel in all registers—and many valve options on the market do not meet our pressure-test standards—S.E. Shires chooses to produce all of their valves in house. They thoroughly test for tight fit and perfect action at every stage of manufacture.

Bass trombone double valve sets can be ordered with either independent (inline) or dependent (stacked) valve configuration:

• Independent (inline): F and D valves are connected in parallel—each can be used independently. This is by far the most popular bass valve configuration.

• Dependent (stacked): F and D valves are connected in series—D valve can only be accessed if the F valve is engaged. This allows the build of the valve section to include a tapered neckpipe. Some players prefer the sound and stability of this system, and its relatively efficient feel in the low register.

Straight Neckpipe: This neckpipe (no valve—also known as a gooseneck) is interchangeable with the valve section, and can be ordered to convert any orchestral (.525- or .547-inch bore) tenor or bass into a straight trombone. It eliminates the valve altogether for an open feel and brilliant sound, with quick response—a popular option for soloists, principals, and commercial players.
