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 and medium bore tenor trombones only. A large-bore horn needs the large-shank version of the same model.
Detail 02
Mid-size rim. Enough room for a full low register without the endurance cost of a 51 or 52.
Detail 03
Standard bore through the mouthpiece. Balanced resistance — neither free-blowing nor tight against the air.
Detail 04
Softer, warmer feel on the lips than silver and won't cause nickel reactions. Slightly more grip when the rim gets wet.
Detail 05
The 47 has the standard rim; the 47C4 adds a wider, semi-flat rim if you want more contact area.
Detail 06
The 46 is a touch smaller and aimed at beginners. The 47 is the size most players settle on long-term.
Final check

Product questions
Straight answers to the questions shoppers most often ask about this product.
No. A Bach 42 is a large-bore tenor and takes a large shank. You need the large-shank version of the 47.
It plays slightly softer and warmer on the lips and avoids nickel allergy reactions. Tone difference is minimal — the cup and rim shape do that work.
Yes. It's a common step-up size that works for students and professionals alike, with solid response and intonation across the range.
Small-shank euphoniums take this shank, but the 47 cup is shallow for euphonium. The 51D or 52D suits euphonium tone better.
