This is a metal mouthpiece that was used for a Gottsu tenor saxophone. It was released around 2018 and is a model developed using the same materials as vintage mouthpieces, based on a Florida Link, with a modern touch. It's a low baffle mouthpiece that can produce both bright and dark tones, making it suitable for jazz, funk, and other genres. There is some discoloration as I didn't use a mouthpiece patch, and there are some scratches on the part where the ligature touches, but there are no problems with normal use. When shipping, I will pack it in the pouch and plastic case that came with the purchase. Thank you for looking.
