Decades of dedicated research have revealed
a vastly superior way to proportion brasswind mouthpieces.
All BbTrumpet models
have the same internal volume of air. The internal contours are then varied to assure uniform pitch.
Our backbores
are unique and they assist related cup sizes to perform with maximum effectiveness.
Cornets and Flugehorn models use similar cup
sizes, but with different backbore sizes for
each type of instrument.
