For many decades, Breslmair has been producing quality trumpet mouthpieces for the classical trumpet player;
But from today, we can also offer a super lead playing underpart!! (check the videos)
 
I have choosen to have the piece as an underpart, so that every player can choose his own preferable rim! All standard rims fit perfectly on the cup (standard rims with -G size).
 
The cup is of course shallow and the throat is small. The backbore is specially made to fit this combination.
