The Chedeville SAV produces a beautiful warm sound with effortless response. We took everything we have learned from our previous mouthpieces and rolled them into one amazing mouthpiece that is priced so that serious students can afford it. The Chedeville SAV mouthpieces are created using industry standard German Hard Rubber. Because we are not using our proprietary Chedeville Rubber, we can pass on significant savings to the customer. This is a favorite of band directors for its ability to blend in with a section.
