This Courtois AC280BO Large Bore Tenor is a pre-owned professional-level trombone that remains in excellent condition, showing only minor cosmetic wear and no evidence of heavy use or repairs. It features an 8.5" yellow brass bell paired with a lightweight nickel silver .547 bore handslide, offering a free-blowing, resonant response across all registers.
The open wrap F-attachment rotor valve design enhances airflow and promotes smoother transitions into the lower register. Slotting is accurate and true, and the instrument’s overall feel is both comfortable and agile—ideal for players transitioning into large bore tenors for the first time.
This model is often compared favorably to the Bach 42BOLT, with similar playing characteristics at a more accessible price point. It includes the original factory Courtois case in good condition, with only a few exterior scuffs. No service is required—this horn is ready to play.
Why choose this model over a new one? With a current new price tag exceeding $2,100, this gently used AC280BO represents excellent value for advancing players or parents seeking a quality upgrade without the new-instrument cost.
Looking for a great first trigger trombone under $2K? This one checks all the boxes for performance, reliability, and affordability.
