What it does

Shaped as a 1-1/2C mouthpiece so it fits where your Bach trumpet mouthpiece goes
Standard 1-1/2C rim and cup shape so you can practice your normal playing routine
Made to order in the USA once you place your order
A low-cost option for backup or practice so you always have a spare on hand
Compact size shaped to sit right on your trumpet's leadpipe

1-1/2C Bach Trumpet Mouthpiece sits on your trumpet's leadpipe just like the mouthpiece you already know. It is shaped to match the classic 1-1/2C size, with the same rim and cup shape trumpet players expect.

This piece is made for Bach trumpets. It gives you a spare mouthpiece to keep in your case, use for practice, or hand to a student who needs one. The shape follows the original 1-1/2C design, so it looks and sits like the mouthpiece you use every day.

Each one is made to order in the USA after you place your order. It is a simple, budget-friendly option to have on hand so you are never stuck without a mouthpiece.
