Gottsu hl 2024 metal tenor saxophone mouthpiece, tip opening is 110 (equivalent to Otto Link 8)! - Brand: Gottsu - Model: hl 2024 metal 110 - Accessories: Case, ligature - Material: Tin alloy Thank you for viewing. This mouthpiece was purchased at a musical instrument store and used once (for about 3 hours). I am selling it because the tip opening didn't suit me. The material is very good, and despite being a high baffle, it produces a dark, thick, and complex sound like the old black Dukoff. Also, the build quality is excellent, so the response is very fast and the operability is good, making it feel like a mouthpiece that combines the best aspects of Dukoff and Guardala. I didn't use this particular mouthpiece because the tip opening didn't suit me, but I have purchased a new one with a slightly larger tip opening and am using it as my main mouthpiece! I used a patch when playing, so it's like new. Ligature, cap, and case are included!!
