The Bach Commercial series mouthpiece is designed for working trumpeters. Based on the original Vincent Bach designs, the Commercial model is optimized for the demands of lead and section trumpet players. The outside shape of the mouthpiece has elements of both the standard Bach and MegaTone models. The heavier body helps enable projection and power. The rim is a somewhat flatter, more comfortable cushion design for players who keep the horn on their face for extended periods or who frequent the upper registers. Specs:
