Roy Benson Bb Trumpet Roy Benson TR-403

An ML bore trumpet designed to gain breadth and personality

With its ML bore (intermediate diameter), this trumpet fits a "all-terrain" approach: free enough to carry in an ensemble while remaining stable for working on intonation and articulation. Its bell more open than the TR-202 reflects a clear choice: favoring a more natural breath sensation and wider projection. The reinforcement with rings contributes to the overall solidity and a more coherent response, especially at sustained volume.

For which musicians and styles?

This trumpet is ideally suited for intermediate to advanced players seeking an expressive instrument capable of adapting to various contexts. The ML bore and more open bell are particularly suitable for playing situations where one wants to fill the space without forcing: marching band, wind orchestra, pop music, big band, or jazz (brass section). Its slightly darker character may also appeal to trumpeters wishing to move away from an overly bright timbre while maintaining precision in articulation.

Sound, response, and finishes: roundness, stability, and comfortable feel

The choice of a rose brass leadpipe directly influences the playing sensation: the sound production feels more flexible, with a tendency to smooth out harshness and enhance the warmth of the tone. The resulting slightly darker sound is interesting for gaining depth without losing the ability to cut through a section. The nickel silver outer slides provide good wear resistance and smooth action, useful daily for adjustments. Mechanically, the fine steel pistons aim for fast and precise action, essential for articulation and clean transitions.

Ergonomics are carefully designed for real playing: finger hook on the 1st valve to easily refine certain notes, fixed ring on the 3rd valve slide for a stable grip, and two-piece 3rd valve slide to facilitate adjustment and maintenance. A water key on the main slide simplifies condensation drainage during rehearsals. Finally, the silver-plated finish gives a professional look and contributes to a feeling of robustness, with a classic aesthetic highly appreciated on stage and in ensemble settings.

Recommended compatible accessories

To get the most out of your instrument daily, plan for appropriate valve oil, slide grease (for the main slide and tuning slides), as well as a trumpet cleaning swab for internal maintenance. A soft cloth is also recommended to preserve the silver finish after each session.
