The Vandoren B Series Bass Clarinet Mouthpieces are indisputably the best bass clarinet mouthpieces out there. Replicating the B44, the B45 is the same mouthpiece except it has a larger tip opening and is very responsive.
Not only is there better tone from the instrument, but there is significantly better performance through the high and low transitions as well as greater range - especially in the higher register.
