Experience an open and vibrant sound across all registers.

The Antoine Courtois AC280BO Performance Series F-Attachment Trombone provides intermediate players an instrument that will grow with their skill. Featuring an open-wrap F-Attachment, the AC280BO seamlessly transitions between registers for a consistent tone from the lowest notes to the highest. The .547" bore and 8.5" yellow brass bell generate a warm, full sound with plenty of projection. An adjustable thumb trigger allows for maximum comfort whether playing with or without the F-Attachment engaged. Overall, the AC280BO delivers an open, resonant tone and responsive feel that inspires musical expression.

Open-Wrap F-Attachment Provides Seamless Transition Between Registers
The open-wrap F-Attachment gives you access to alternative slide positions for lower notes as well as a smooth transition between the F-Attachment and standard slide. You'll experience consistent tone and response from the lowest to highest registers, allowing you to focus on your technique and musicality rather than adjusting to changes in the instrument. The open wrap also provides a free-blowing feel and even weight distribution for comfortable playability over long practice sessions.

Progressive Bore and Large Bell Create a Robust, Resonant Tone
The .547" bore and 8.5" yellow brass bell are designed to produce a warm, resonant tone with full projection. The progressive conical bore opens up gradually from mouthpiece to bell, generating rich overtones and a broad range of dynamics. The two-piece bell focuses the sound while enhancing resonance. Together, these features create an open, vibrating tone that carries in both small and large performance spaces.

Adjustable Thumb Trigger Accommodates Different Hand Sizes
The adjustable thumb trigger allows you to customize the position of the F-Attachment for maximum comfort and ease of use. Whether you have small or large hands, you can place the trigger in the optimal spot to engage and disengage the F-Attachment smoothly. This flexibility means the AC280BO can be comfortable for a wide range of players with different needs, from beginners to more advanced musicians.

Premium Materials Provide Durability and Long-Lasting Value
Constructed from durable yet lightweight yellow brass, the AC280BO is built to withstand years of regular use. Lacquer finish protects the brass while maintaining tone quality. Nickel silver outer slide tubes allow for quick, smooth slide action. Pads and felts are high quality for minimal maintenance needs. The included mouthpiece and case provide everything you need to start playing right out of the box.
