Courtois AC-502 Independent Bass Trombone – Archive
The Courtois AC-502 bass trombone is a finely crafted instrument made in France, designed for serious players seeking a versatile, modern bass trombone setup.
This example features an independent valve system, allowing for flexible tuning options and smooth low-register transitions. It has a 9.5" yellow brass bell, providing a rich, broad sound with excellent projection and warmth — ideal for orchestral, symphonic band, or large ensemble settings.
This instrument was single-owner, lightly used, and remains in like-new condition, showing minimal signs of play or wear. It offers a professional-level playing experience without the price tag of a brand-new model.
These Courtois bass trombones are not commonly found on the used market, making this a rare opportunity for advanced students or professional players looking for a high-quality European-made bass trombone.
The included case is lightweight yet protective, making it convenient for travel and storage.
Where are Courtois trombones made?
Courtois trombones were originally handcrafted in France, beginning in 1803. Today, the brand is part of the Buffet Crampon Group, a major European instrument company with multiple renowned brands under its umbrella. While certain parts or sub-assemblies may come from different locations, professional-level Courtois trombones like the AC-502 are still assembled and finished in France, preserving their signature craftsmanship and tonal quality that players expect.
This instrument is now archived and no longer available.
