S.E. Shires Custom Series Tenor Trombone Valve Section
The valve controls much more than the low register; it can be used to focus or loosen the feel in the center of the instrument. The articulation, sound density, and stability of the sustained tone is affected by each valve type.
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 their 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.
Large- and medium-bore tenor valve sections can be made with a choice of five different valves: the S.E. Shires rotary valve, the S.E. Shires twin valve, the S.E. Shires axial-flow valve, the S.E. Shires dual-bore valve, or the S.E. Shires Tru-Bore™ valve (U.S. Patent 7112735).
A gooseneck, interchangeable with the valve section, can be ordered to convert any orchestral tenor or bass trombone to a straight instrument.
