Description
The MB 41PWB is a correctional mouthpiece which is a ported mouthpiece that rotates on to the tongue while collapsing on to the outer lip and bars. The port has a tiered design with the base being quite wide with rounded corners while the top is narrower and has pronounced corners. This offers nearly the same comfort and tongue relief that Level 3 mouthpieces have in a Level 2-3 bit.
