This pre-owned Bach 50BO Bass Trombone is a mid-2000s make in excellent condition. The 50BO is a single-valve bass trombone with an open wrap design, making it an ideal choice for players who prefer the feel and resonance of a lighter, more streamlined setup compared to dual-valve models.
The instrument features a 9.5" yellow brass bell and a .562 standard weight bass slide, both of which contribute to the rich, powerful sound that Bach bass trombones are known for. The open wrap F-attachment allows for smoother airflow and improved response, giving players a freer, more open feel when engaging the valve.
This horn has been pro-player owned since new and has clearly been well cared for. It shows only minimal signs of wear: the lacquer is in excellent shape, the valve is quick and quiet, and the hand slide plays perfectly. No service is needed to improve its appearance or playability — it is ready to go straight into performance use.
The 50BO is a versatile option. It makes an excellent first bass trombone for a younger player stepping up from a tenor, for a professional or freelancer who wants the clarity of a single-valve setup, or even for a school looking for a durable and dependable bass. Built to last, these instruments have long been trusted as workhorses in orchestral, band, and educational settings.
The trombone comes with its original case, which is also in excellent condition. A mouthpiece is not included.
