Overview
This Bach Corporation-era 11 small-shank trombone mouthpiece came from an estate collection and was documented in like-new condition. It showed very little evidence of previous use and had been professionally chemically cleaned and silver polished before evaluation.
Manufactured during Bach’s earlier Elkhart Corporation era, this mouthpiece reflects a period of production that preceded modern fully CNC-based manufacturing. Mouthpieces from this era remain popular with players who appreciate the feel, response, and individual characteristics of earlier Bach examples.

Model Comparison
The Bach 11 has an approximately 24.70 mm inside rim diameter, placing it very close in size to familiar Bach 7 and 7C mouthpieces at approximately 24.75 mm. The difference of roughly 0.05 mm is extremely small, allowing many players to retain a familiar rim diameter while moving to the deeper cup profile of the Bach 11.
Compared with a traditional C-cup mouthpiece, which generally provides a brighter tonal profile and more immediate response, the deeper cup of the Bach 11 produces a fuller, broader, and more covered sound.
Player Perspective
The Bach 11 can be an interesting choice for players who are comfortable with the general rim dimensions of a Bach 7 or 7C but want additional cup depth and tonal breadth. Its proportions combine the familiar feel of a medium-width rim diameter with a deeper, more resonant cup.
The result is a mouthpiece capable of producing a richer and more covered tonal character without requiring the player to move to a substantially larger rim diameter.
Condition Summary
This mouthpiece was documented in like-new condition with very little evidence of previous use. The rim, cup, and shank were clean and true, and the silver-plated finish presented very well. It had been professionally chemically cleaned and polished and was ready to play at the time of inspection.
Historical Reference
Bach Corporation-era mouthpieces provide a useful reference for comparing different periods of Bach production. This Model 11 also documents one of the less frequently encountered combinations in the Bach trombone mouthpiece range: a rim diameter close to the familiar 7 and 7C paired with a substantially deeper cup.
This specific Bach Corporation-era 11 mouthpiece is no longer available. The page remains online as a historical reference for musicians and collectors researching vintage Bach trombone mouthpieces, dimensions, and production periods.
