Classic Trumpet Mouthpiece; Silver Plated; 4B

This mouthpiece was originally based on the Vincent Bach 7C, one of the most popular trumpet mouthpieces in the world. The 4B has a medium depth U-shaped cup and a medium-large bore. The inner edge of the rim was designed to be a little less sharp than the Bach version, giving greater flexibility and a more comfortable playing experience. The 4B works equally well on Bb, C and D trumpets, and is the perfect size for beginners and intermediate players. It produces a solid and bright sound, and is one of our best-selling trumpet mouthpieces.

Cup diameter: 16.50mm.
Rim width: 5.18mm.
