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 small bore tenor and alto trombone receivers only. A large bore horn needs the large shank version.
Detail 02
On the narrower side for tenor, which favors endurance and upper register over sheer low-end volume.
Detail 03
A tighter throat than the symphonic models. More resistance to lean on, quicker response, less air needed to fill it.
Detail 04
Balances the tight throat. Keeps tone even top to bottom rather than spreading at loud dynamics.
Detail 05
A middle-of-the-road rim. Enough cushion for long sets without so much surface that flexibility suffers.
Detail 06
Feels slightly slicker and warmer on the lip than silver, and avoids nickel contact for players with skin reactions.
Final check

Product questions
Straight answers to the questions shoppers most often ask about this product.
Small shank fits small bore tenor and alto trombones; large shank fits large bore tenor and bass horns. They are not interchangeable — the taper differs and the wrong one will not seat.
Yes. The 25mm cup and 6.24mm throat give clean, even tone with quick response, which is what small bore jazz playing asks for.
Feel and skin contact. Gold is slicker on the lip and contains no nickel, which matters if silver or nickel plating irritates you. Sound difference is minimal.
Yes. Alto trombone is one of the intended uses for this size — it takes a small shank and the clean, even tone suits the instrument.
