For tenor saxophone. This is a vintage Otto Link with the word "super" in double quotation marks (""). It produces a thick, mellow sound characteristic of the tenor saxophone. It's also easy to produce subtones. My personal impression is that it has a very tasteful tone and feel, making me want to play it more and more. The opening is 7☆. I mainly use a rubber mouthpiece now, so I've only used this product a few times since I purchased it used in October 2024. There are traces of a patch that was attached. The original ligature and cap are also included. Thank you. #OttoLink #Mouthpiece #Vintage #TenorSaxophone #Metal
