I was given a clarinet recently, as a "thank you" for something I did for my partner's friend. It's a Buffet B12, resin model and judging from the serial number (552***) I think it's about 10 or 12 years old. My question is about the mouthpiece, which is scuffed and marked along the lay, and there are some tiny marks on the top left corner of the tip (when looking into the reed / tip gap.) I have got sound out of it, but I'm not sure if this could be improved with even an inexpensive beginner's mpc, without scuffings? The mpc is a Vandoren, although the model number is partly worn off. I think it may be B45. I have attached 2 images of the scuffs and 1 of the name and model numbers, for any suggestions that you might care to offer. I am really only asking about the playability (or otherwise) of the mpc and the quality of the model for a beginner. Would perhaps a $15 student model be as good - and even better than the one in the photos. Thanks for any suggestions.
