Mouthpieces

ACB Standard Series

These Standard line mouthpieces are formulated for players playing a conventional "stock" mouthpiece. For instance if you play a Bach 3C a good place for you to start is with our 3C. While our 3C does not equal theirs it’s a great starting point for each client. Here is some additional information about your options:

• Each Standard line comes with a custom throat mated for optimal performance with each cup, rim and backbore.  If you require a custom throat size this  can be ordered if you prefer. Please note all other alterations done to the mouthpiece will make the piece a custom order thus removing the return option.

• Each piece can be ordered as a one piece blank. Custom Blanks are available.  These are available in Silver or Gold Plate.
