The new Bach Commercial Mouthpiece is designed for everyone from the aspiring lead trumpet player, to the seasoned veteran who is looking for something new.

Two different cup designs:

• A Shallow Cup for the S models
• Modified V Cup for the MV models

All models come with a #56 backbore, a #27 (.144") throat, and modified comfort rim with a flatter top.

The outside shape of the mouthpiece has elements of both the Standard Bach 351 Models and the Bach MegaTone K351 Models. All combined, this creates a great feel with the projection needed to "Take the lead!"
