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
Standard trumpet shank. Fits trumpets across brands; does not fit cornet, flugelhorn or any larger-bore brass.
Detail 02
The 3C reference points at a common general size, but this is a signature cut, so feel won't match a plain 3C.
Detail 03
Dimensions were set by one player. Order by the exact model name rather than translating from another brand's chart.
Detail 04
Specialist pricing. Reasonable for a considered swap, steep if you're still figuring out what cup you want.
Detail 05
A dedicated mouthpiece maker with its own sizing language, so comparison tables from other brands are rough at best.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
No. The name references a familiar size, but this is a signature cut with its own dimensions. Expect a different feel.
Any trumpet with a standard receiver, yes. It won't work on cornet or flugelhorn, which take different shanks.
Years, until the plating wears through at the rim. Once bare metal shows, replace it rather than continuing to play it.
Buy this if you already know you want this cut. If you're still searching for your size, start somewhere more common.
