Bach's Commercial models are optimized for the demands of lead trumpet players with a heavier body that helps enable projection and power. The rim is somewhat flatter - a more comfortable cushion design for players who keep the horn on their face for extended periods time and in the upper register.

Offered in two cup designs (S and MV) and four diameters (largest to smallest: 3, 5, 7, and 10.5). All models come with a #56 backbore, a #27 (.144") throat, and modified comfort rim with a flatter top.
