Thank you very much for viewing. This is a Meyer alto saxophone mouthpiece, 5MM. Regarding the condition, there are some stains and scratches, but the baffle, side rails, and table are in very good condition. Currently, G-tuning, which is done by Mr. Gottsu Goto's careful handwork, is not performed. It is exceptionally easy to blow, easy to breathe into, and has excellent control accuracy. The tone is bright and deep, and the mouthpiece has a full sound. (This is just my personal opinion, so please use it as a reference.) Regular Meyer mouthpieces, in particular, often have individual differences, so please consider this one. If you have any other questions, please feel free to comment. #Yamaha #Selmer #TheoWanne #Yanagisawa
