Love my new mouthpiece!

It has been amazing to play in the upper register with so much consistency! I’m still working out which ligature/reed combination I like but overall very happy!

Incredible projection with a great rich sound.

Most bass clarinet mouthpieces that project get less than a desirable tone quality, while others that get a beautiful sound seem to lack the projection to compete with the brass projection. The Hawkins H is a wonderful bass clarinet mouthpiece that gets wonderful projection while getting a beautiful, characteristic bass clarinet sound. Beautiful in all registers of the instrument. Articulation is clear and precise. At different I have enjoyed playing the Selmer C*, Selmer C**, Vandoren Black Diamond, Pomerico, MoBa, and CG. I loved all of them. The new Vocalise H bass clarinet mouthpiece will remain for a very, very, long time. Plays great on Silverstein Ambipoly bass clarinet and tenor saxophone 3.5 reeds and Vandoren V-12 3,5 reeds. !

Comfortable Right From the First Note

I never liked a mouthpiece Immediately, before, always takes a while to adjust. But my new "G" Bass Mpc was comfortable right from the first note. It's "G"-ness was apparent right away. NO rasp in lower Reg, just solid velvety smoothness. I have the Bb Model too. I'm very happy with the sound and feel of this new Material they are made from. AND the reasonable Price! You could have charged a lot more, and people would still buy them. Kudos to Richard!

Great to Play

The Vocalise bass clarinet mouthpieces are a joy to play. The R is the mouthpiece I wish I had when playing the bass clarinet for the first time. It’s so even and controlled over the entire range. That said, the G model is my favourite one to play because of its’ consistent tone over the entire instrument. As a doubler, it checks all the boxes I need from a mouthpiece. It has a wonderful tone, it’s very responsive and it is flexible enough to play aggressively on a jazz or theatre gig, but still elegant enough to play my favourite classical pieces.
