Overview
This S.E. Shires Custom Series BII 7YM detachable flare bass trombone bell package includes a like-new detachable flare bell (screw bell) and matching Marcus Bonna case. Both pieces are in outstanding condition with no prior damage or repair history, and the lacquer on the bell remains fully intact.
The BII 7YM DF bell features a 9½-inch yellow brass flare with gold brass threaded collar, designed for Shires modular bass trombone setups. Detachable flare systems allow the bell to be separated from the body, reducing overall case size dramatically while maintaining full professional performance capability.
The included Marcus Bonna screw-bell case is compact, lightweight, and purpose-built for Shires detachable flare bass trombones, making travel easier for airline flights, public transit, or campus use.
As an authorized S.E. Shires Pro Shop since before the Eastman acquisition, we’ve worked with many detachable flare setups and helped players configure travel-friendly Shires bass trombones.
Player Perspective
From a professional player’s standpoint, detachable flare bells offer portability without sacrificing sound quality. The threaded collar adds a small amount of weight near the bell throat, which can help focus projection and produce a centered, powerful tone.
Many touring and orchestral players choose detachable flare Shires bells because they can carry a compact case while keeping their preferred bell sound and modular flexibility. Paired with a quality case like a Marcus Bonna, the system is practical and durable for regular travel.
