Key Features
The Courtois Mezzo Bb/F Tenor Trombone, Large Bore is suited to developing players progressing through ensembles, brass bands, and wind bands. Produced by Antoine Courtois, one of France's longest-established brass instrument makers and now part of the Buffet Crampon Group, it combines proven design principles with features tailored to advancing musicians. Based on the Courtois Legend series AC420BO, it pairs a large 13.89 mm bore with an open wrap rotor system for a balanced, responsive playing experience.
The open wrap design helps maintain a natural airflow, while the traditional valve provides the flexibility needed for more demanding repertoire. A lightweight nickel silver outer slide keeps handling comfortable during longer rehearsals, and the adjustable thumb trigger allows you to tailor the setup to your preferred playing position. Finished in clear lacquer with a two-piece yellow brass bell, the AC280BO offers a dependable setup for progressing performers. A deluxe ABS backpack case, mouthpiece, and cleaning cloth are included, so you're ready for lessons, rehearsals, and performances straight away.

The AC280BO takes its design cues from the Courtois Legend series AC420BO, bringing features from a higher-level instrument into a model aimed at developing players. Antoine Courtois has been building brass instruments since 1803 and has earned a reputation among performers for thoughtful design and reliable craftsmanship. This heritage is reflected in the AC280BO's specification, giving you an instrument that supports progression while remaining approachable and comfortable to play.
The Bb/F configuration features an open wrap traditional rotor system that promotes a smooth airflow path through the instrument. This design helps create a more natural feel when engaging the valve, making transitions between registers feel more consistent. Combined with the large 13.89 mm bore, the result is a responsive playing experience suited to ensemble work, solo repertoire, and the technical demands that come with advancing through grades and group performances.
Designed with younger performers in mind, the AC280BO includes practical features that support longer practice sessions and rehearsals. The lightweight nickel silver outer slide offers smooth operation and balanced handling, while the adjustable thumb trigger helps you find a comfortable playing position. The forged water key assembly provides dependable operation, helping make regular maintenance straightforward. Together, these features create an instrument that feels manageable as your confidence and technique continue to develop.
As part of the Buffet Crampon Group, Antoine Courtois benefits from the resources and instrument-making expertise of one of the world's most recognised wind and brass instrument manufacturers. The AC280BO reflects this commitment to quality through its clear lacquer finish, two-piece yellow brass bell, and dependable construction. Plus, it arrives with a deluxe ABS backpack case, mouthpiece, and cleaning cloth, providing everything you need to transport, maintain, and enjoy your instrument from day one.
