What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.

Detail 01
Fits the narrower receiver taper on small- and medium-bore tenor trombones. It will not seat properly in a large shank horn.
Detail 02
Cut for tenor. Bass trombone uses a different shank and a larger cup, so this is not a substitute.
Detail 03
A Bach size code. Rim and cup are fixed by that number, so any 6-1/2AL plays the same as the one you already know.
Detail 04
Standard replacement pricing rather than custom or hand-finished. You are buying a known size, not a bespoke fit.

Product questions
Straight answers to the questions shoppers most often ask about this product.

No. Bass trombones take large shank mouthpieces. This is a small shank tenor piece and will not seat correctly.
It is made for tenor trombone. Shank taper decides fit, not the instrument name, so check your receiver before ordering.
They are different size codes in the same Bach small shank line. The rim and cup differ, so feel and response differ. Shank fit is identical.
