This S.E. Shires BII 1G Bass Trombone Bell Section features a 10" gold brass bell in standard weight construction. Built with the Type II taper and higher copper content, this bell delivers a rich, dark, and expansive tone—ideal for symphonic and ensemble work where blend and warmth are essential.
The BII 1G was previously used in a professional playing environment and remains in excellent playing condition with only minor cosmetic signs of use. It's fully compatible with all Shires bass trombone valve sections, including Custom Series and the modular Q36 components. This makes it a great option for a player looking to explore the sonic depth of gold brass while staying within the flexible Shires modular system.
A 10" bell is slightly larger than the standard 9.5" configuration and gives the player a wider spread in tone, especially useful for bass trombonists seeking more room and resonance in their sound. While not every player prefers the 10", those who do often find it adds a welcome presence and body to their low register.
This bell section has already been sold, but it stands as a reference for other musicians exploring Shires bass bell configurations or comparing historical availability.
What is the difference between a 10" bass trombone bell and the standard 9.5"?
Most bass trombonists play on a 9.5" bell, which is considered the standard size for modern orchestral and ensemble settings. However, some players prefer a 10" bell for its slightly broader, more expansive sound profile. The increased diameter offers a wider spread in tone, which can enhance the richness and warmth of the low register—especially in large ensemble or symphonic contexts.
While the 10" bell isn't the ideal choice for every player or musical style, many find it offers a more enveloping feel and better supports the naturally large sound produced by a .562 bore bass trombone. It's not just louder—it creates a larger tonal footprint, and for players seeking more room in the sound, the difference is meaningful.
This Shires BII 1G bell section is now archived as a reference for musicians considering a gold brass upgrade or exploring the differences in Shires bell configurations.
