The S.E. Shires Custom BII 7GM bass trombone is a versatile instrument with a clear, pure sound and the consistency, playability, and projection that has made S.E. Shires trombones the favorites of professionals the world over. The unique S.E. Shires 7GM bell combines the quick response and color of a one-piece bell with the centered feel and expansive tone of a two-piece bell. The BII bell taper in gold brass produces a broad, rich sound that is very balanced and flexible throughout the range of dynamics. The patented S.E. Shires Tru-BoreTM valve blends a broad, rich sound with an efficient, centered feel.

Recognized as a leader in brass instrument design and innovation, S.E. Shires Co. sets the benchmark for blending traditional craftsmanship with high-tech consistency and precision. 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. S.E. Shires makes beautiful instruments, built to last for many years. Mouthpiece and case not included.

Extraordinary Craftsmanship

This instrument is one of the finest I have ever played. The tone color you can get out of this horn is amazing throughout the range of the instrument. Playing in a large ensemble, I hold my own. On solo repertoire I am able to get the dark round tone that I have been striving for. The valves allow for an open low range and have allowed me to improve my low range technique. This instrument does not break up or "bark" at fuller dynamics like some other basses that I have played on. This is by far the best investment I have ever made.
