This Bach Corporation 15 small shank trombone mouthpiece was produced during the Elkhart, Indiana era, manufactured between approximately 1963 and the late 1970s. Mouthpieces from this period were made using traditional lathe-cut production methods rather than modern CNC machining, a process many professional players associate with the classic Bach feel, consistency, and response that later production often differs from.
The Bach 15 has long been regarded as a versatile, middle-ground small-shank size within the Bach lineup. With a 24.40 mm rim diameter, it sits comfortably between smaller specialty sizes and larger orchestral-oriented small-shank mouthpieces. By comparison, a Bach 17 measures approximately 24.20 mm, a Bach 12 measures 24.50 mm, an 11 measures 24.70 mm, and a 7 measures 24.75 mm. This places the 15 in a sweet spot that balances comfort, flexibility, and tonal stability.
The cup profile offers a clear, centered sound without excessive brightness, making the Bach 15 suitable for a wide range of playing situations. It works particularly well for small-bore trombone players who want a mouthpiece that can handle section work, jazz, commercial playing, and general-purpose use without feeling restrictive in the upper register or overly broad in response.
This example is offered in excellent condition and has been professionally cleaned using a chemical bath, followed by a careful silver polish. The mouthpiece is clean, smooth, and fully player-ready, with no issues affecting fit, response, or playability. It retains the solid, familiar feel that has made Elkhart-era Bach mouthpieces consistently desirable among players and collectors.
The Bach 15 remains a strong choice for players seeking a classic Bach small-shank mouthpiece with a proven design, traditional manufacturing quality, and broad musical applicability.
