Overview
This Bach 36B trombone from the early 1980s represents one of Bach’s most versatile medium-bore designs. Built around the classic .525 bore slide and F-attachment bell section, the Model 36B has long been favored by players who need a single instrument capable of covering a wide range of musical styles.
This particular instrument received full shop service, including a chemical cleaning and mechanical adjustments to ensure proper playing condition. The horn had experienced previous cosmetic repairs, but those areas have been cleaned up and stabilized, leaving the instrument structurally sound and fully playable.
The finish is mostly raw brass, with much of the original lacquer removed through age and wear. While the appearance is not pristine, the instrument remains a strong player, delivering the flexible response and tonal breadth that the Bach 36B is known for.
The trombone includes the original case, which remains functional though in fair cosmetic condition.
✦ Historical Perspective
The Bach 36B has long served as a bridge between smaller jazz trombones and large orchestral instruments. Its medium-large .525 bore offers more depth and projection than small-bore jazz horns while still retaining the agility and flexibility needed for varied musical settings.
Because of this balance, the 36B became widely used in:
• concert band
• chamber ensembles
• pit orchestras
• teaching studios
• advancing student programs
Many players appreciate the way the 36B can adapt to different mouthpieces and musical contexts. With a larger cup mouthpiece, it can produce a broader symphonic sound, while a smaller mouthpiece allows it to function effectively in lighter commercial or jazz settings.
