This is my mouthpiece almost from the start. My first mouthpiece was a regular B45 (I try also M30, M13 and the ones that come with the clarinets).
It is very simple to have good sound with it. That, for me, is one of the most important aspects to have in account when you buy a mouthpiece, or a reed, or even a clarinet. having a good sound have to be worked, but, at same time, have to be natural.
Of course that every person has a different way to play. So, you will have to try some different mouthpieces to understand what is the mouthpiece that will help you play well and with a good sound with naturalness.
