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 trombone receivers only. On a large-bore horn it sits loose and won't seal.
Detail 02
A moderate rim size. Enough room for a full sound without the endurance cost of a wide bass-trombone rim.
Detail 03
Medium rim. Spreads pressure across the lip better than a narrow rim while still allowing flexible slurs.
Detail 04
A fairly open throat for a small shank. Adds body and low-end weight, and takes a steadier air stream.
Detail 05
Balances resistance against openness — keeps the high register solid without the sound going thin or edgy.
Detail 06
Slightly grippier on the lip than gold plate and hard-wearing, but it can irritate skin sensitive to silver.

Product questions
Straight answers to the questions shoppers most often ask about this product.
Only if your horn takes a small shank — typically a small-bore tenor. Large-bore tenor and bass trombones need the large-shank version.
5BS is small shank with a 6.87mm throat. 5AL is large shank, wider at 25.73mm cup with a 7.30mm throat and barrel backbore for symphonic projection.
It works for small-bore jazz playing, with a solid high register and more body than a stock piece. The 12CS is Denis Wick's dedicated jazz model.
Wash with warm soapy water and a mouthpiece brush, then dry it. Avoid abrasive polish on the rim — it thins the plating over time.
