Offered in four classic Bach rim diameters (3, 5, 7, and 10.5), the Bach Commercial trumpet mouthpieces provide two distinct cup designs: a Shallow Cup or Modified V Cup, giving you the flexibility to find the perfect feel for your performance.

The exterior design of these mouthpieces incorporates elements from both the Standard Bach Standard Models and the Bach MegaTone models, engineered to enhance note slot accuracy during upper register playing.
