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
A fixed cup, rim and throat combination. You take the whole profile as designed; nothing about it is adjustable.
Detail 02
Fits trumpet receivers only. A cornet or flugelhorn will not take it without the correct shank.
Detail 03
Cosmetic marking that identifies the model. It does not change how the piece plays.
Detail 04
Above stock student mouthpieces, below custom-made work. A one-time purchase that outlasts several horns.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
It uses a standard trumpet shank, so it fits standard trumpet receivers. It will not fit cornet or flugelhorn without the correct shank.
Not really. It is a specific signature profile. Beginners are better served finding a comfortable rim size first, then moving to a piece like this.
No. Mike Vax #1 is the model marking. Cup, rim and throat determine how it plays.
No. This is the mouthpiece by itself. Budget separately for a pouch or case if you want one.
