This is a Morita Wind Instruments ligature, the Second Impact tenor saxophone model S7. I purchased it several years ago at Yamano Music Sendai (now closed). (Retail price including tax: 24,200 yen) I have used it with Otto Link rubber mouthpieces, Vandoren V16, D'Addario Jazz Select, and Selmer S90. It is fully functional, but there are minor scratches and scuffs. The screws move normally. In terms of how it sounds, it produces a clean, unadulterated tone. It efficiently transmits the reed's vibrations to the instrument. I think it's more suited for classical players who need a transparent tone, rather than jazz players who seek a darker sound. When used with jazz mouthpieces, it produces a refined sound. I believe this ligature is better suited for those who prefer a well-balanced tone (regardless of genre) rather than those who need a bold, raw sound. This is just my personal opinion, but I hope it helps. I am a non-smoker and I do not have any pets. Please understand that this is a used item.
