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
Medium rim diameter, medium cup depth. Bach's most common all-around trumpet size, used across concert band, jazz and orchestra.
Detail 02
Thicker outer wall than a standard mouthpiece. Adds mass, which players describe as a darker, more centered sound and slower response.
Detail 03
Fits standard Bb trumpet and cornet-to-trumpet adapters. Will not fit cornet or flugelhorn receivers directly.
Detail 04
Middle of Bach's range. Enough depth for full tone in the staff without making the upper register a fight.
Detail 05
Same rim as the standard 3C, so the change is in the blank, not what your lips sit on.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
The rim and cup are the same 3C. The outer blank is heavier, which adds mass and typically gives a darker, more centered sound with a bit more resistance.
No. This is a trumpet shank. Cornets take a cornet shank mouthpiece unless you use an adapter.
3C is a standard all-around size, but most beginners start on a 7C, which has a smaller rim that's easier to control early on.
Not directly. Cup depth is unchanged from a standard 3C. Shallower cups help the upper register; this one is about tone and mass.
