Rashawn Ross approached us earlier this year to make him a custom mouthpiece and this is the new model we developed, which may be Dave Monette's new favorite lead mouthpiece size! It has a B2 rim, an extreme "SLAP" cup and a cup depth between a B2L S1 and a B2LD S1. Rashawn plays trumpet with the Dave Matthews Band, and can play triple high C's (and above) with more ease than any player we have ever met!
