The Bach Commercial mouthpieces are designed for everyone from the aspiring lead trumpet player to the seasoned veteran who is looking for something new. Available in two cup designs—shallow cup or modified V cup, these mouthpieces are designed to give the flexibility to get the right feel for you. All models come designed with a #27 (.144”) throat, and a modified comfort rim with a flatter top. The outside shape of the mouthpiece has elements of both the Standard and Mega Tone Bach models creating a great feel, with projection to take the lead.
