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
Bach's wide rim contour. Spreads pressure over more of the lip, which usually trades some flexibility for endurance.
Detail 02
Bach's medium-size grouping. A step off the 7C most students start on, without jumping to a large orchestral cup.
Detail 03
Fits Bpr, C and piccolo trumpet receivers. It will not seat correctly in a cornet.
Detail 04
Wipes clean easily and resists wear, but some players react to plating contact on the lips.
Detail 05
Standard replacement-mouthpiece money. Cheap enough to own two and switch by playing situation.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
No. Trumpet and cornet mouthpieces use different shank tapers. You need a Bach cornet mouthpiece instead.
Wide rim. The contact surface against your lips is broader than a standard Bach rim of the same number, which most players find more comfortable on long sessions.
It is a different size and rim, not strictly better. Players usually move here for rim comfort rather than for a change in sound.
Warm soapy water and a mouthpiece brush, then dry it. Avoid harsh abrasives that wear the plating.
