S.E. Shires Custom Trombones Header
S.E. Shires fabricates its bells, tubing, and valve sections onsite in its Massachusetts factory to exacting standards. The valve components are tested thoroughly for accurate tolerances and perfect action at every stage of manufacture. Shires draws its own slide tubes to precise tolerances, assembling them without tension, and aligning them carefully to assure smooth, trouble-free action that is second to none. This handcrafted approach to instrument construction also ensures that the sound of every S.E. Shires trombone displays incredible depth, complexity and character—giving the player an unrivalled sonic palette with which to work.

Because your physical characteristics and way of playing are as unique as your ideal sound, S.E. Shires designs trombones as a highly flexible component system. The descriptions found on this site represent general observations, which hold true for the majority of players. Components that may work well in one combination or for one player or situation may be poorly suited to others. More important than considering every possible combination is finding the combination that makes sense—and works best—for you.

Our most popular setups are listed on this site as Standard Models, accompanied by an alphabetical product code, e.g., TBBO. These configurations (and only these configurations) ship with case and mouthpiece included. We offer options that can be used to customize those models or to come up with a completely different custom configuration; for customized instruments, cases and mouthpieces are available for purchase separately.

S.E. Shires Trombone Tuning Slides  
Trombone Valve Sections
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 our valves in house. We thoroughly test for tight fit and perfect action at every stage of manufacture.

S.E. Shires Trombone Leadpipes  
Trombone Leadpipes
The leadpipe is the first point of contact with the player after the mouthpiece. It plays an important role in determining the overall feel and sound of the instrument. The diameter of the venturi, the material of the pipe and its length all have a significant effect on the instrument's playing characteristics.
