Shires Custom

Setting the bar for excellence

The TBBSC Shires Custom Bass Trombone is the most popular model in the Shires Custom series, trusted by musicians worldwide for its versatility, exceptional craftsmanship, and tonal excellence. Designed to meet the needs of a wide range of players, from orchestral professionals to soloists and chamber musicians, the TBBSC embodies the artistry and precision that define the S.E. Shires brand.

At its core is the signature BII 7YM bell, which combines the quick response and tonal color of a one-piece bell with the centered feel and expansive resonance of a two-piece design. The BII taper in yellow brass produces a broad, rich sound that is balanced and adaptable across all dynamics. Paired with the axial-flow valve system, which ensures an open and even feel, particularly in the low register, the TBBSC delivers a seamless playing experience. This model continues to set the standard for bass trombones, making it a trusted companion for musicians at the highest level of performance.

TROMBONE OPTIONS

Each Shires trombone is more than just an instrument

Each S.E. Shires trombone is more than just an instrument; it’s a customizable tool designed to meet the specific needs and preferences of every musician.

The S.E. Shires modular system allows players to mix and match various components—bells, leadpipes, handslides, tuning slides, and valves—to create a trombone that is perfectly suited to their playing style and desired sound.

Endless Possibilities, Uncompromised Quality

Because an airtight valve is essential to quick response and centered feel in all registers, S.E. Shires chooses to produce all of our valves. We thoroughly test for tight fit and perfect action at every stage of manufacture.
The valve controls much more than the low register: articulation, sound density, and stability of the sustained tone is affected by each valve type.
All S.E. Shires bells are handcrafted in using traditional techniques. Shires bells—known for their rich sound, easy response, and incredible projection—benefit from decades of experience designing and spinning bells.
Handslides control the initial feel of the instrument. Handslide bore size, width, crook size, alloys and weights are contributing factors for handslides.
Our slide tubing is drawn to precise tolerances and then carefully assembled, aligned, and stress relieved to assure the smooth, trouble-free action that has become the hallmark of S.E. Shires trombones.
Trombone tuning slides can effect resistance, response, and color of the instrument.
S.E. Shires trombone tuning slides are engineered with a unique, smooth, double-radius design. They combine the best characteristics of single- and double-radius tuning slides in terms of timbre, response, and intonation.
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.
