SPECIAL ORDER

A small shank mouthpiece for baritone with a slightly shallower cup than the regular SM4U.

Steven Mead on the SM4X:

I recommend this mouthpiece for anyone who currently plays the current Ultra SM4U and looking for more support and power especially in the upper register. In addition, anyone who currently plays a mouthpiece with the 5 rim should find the step up to the 4X beneficial and very easy to manage.
