Overview
This Bach Corporation Era 6 1/2A small shank trombone mouthpiece was manufactured in Elkhart, Indiana between approximately 1963 and the late 1970s. Bach mouthpieces from this production era are often appreciated for their traditional hand-lathe manufacturing methods, which differ from today’s CNC-based production techniques.
All Bach 6 1/2-series mouthpieces share the same 25.4 mm rim diameter, and the 6 1/2A is no exception. Where the model differs from the more commonly encountered 6 1/2AL is primarily in the backbore design. The 6 1/2A uses a more standard backbore configuration rather than the larger and more open backbore found on the AL version.
The result is a mouthpiece that maintains the familiar Bach 6 1/2 rim feel while offering a slightly more centered and controlled response. Many players appreciate this balance, particularly when pairing the mouthpiece with small and medium bore tenor trombones.
Player Perspective
The Bach 6 1/2A remains a versatile all-around mouthpiece choice, especially well suited for tenor trombones in the .508 and .525 bore range.
Compared to the more open-blowing 6 1/2AL, the 6 1/2A can feel slightly more compact and focused while still retaining flexibility across registers. Articulation remains clear, response is predictable, and the mouthpiece maintains a familiar Bach feel that many players have used for decades.
For players seeking a balance between efficiency, tonal depth, and control without moving into larger symphonic mouthpiece territory, the 6 1/2A continues to be a practical and dependable option.
