This is a Best Brass 5C mouthpiece. I bought it when I was deep in the mouthpiece rabbit hole. I tried both this and the Groove, and this one produces a more straightforward sound, for better or worse. I generally feel it has a soft, smooth sound. Preferences may vary, but I think it's a good mouthpiece. I think it's in good condition, with no noticeable scratches on the rim, shank, etc. It's an American shank. *If there aren't many interested buyers, I will reconsider the price, so please refrain from negotiating discounts. *There is no original box. It will be shipped in bubble wrap. *Shipping is unavailable between December 10th and December 17th. I apologize for the inconvenience.
