Bach Commercial Series Mouthpiece

The Commercial series was designed specifically for lead trumpet players looking for greater depth of sound and volume when playing in higher registers.

The Commercial series starts with a Classic cup, but uses a 27 throat, a 24 backbore and increases the outside mass. Commercial mouthpieces are only available in Shallow and Medium V shaped cups.
