This is a Vandoren carbon fiber ligature for alto saxophones. This ultra-premium, ultra-lightweight ligature is a one-of-a-kind product with no equal. The initial response when you start playing is incredibly fast, yet it's not too light, and it also significantly reduces noise, which I think will greatly increase the number of reeds you can use. I'm selling it because I bought a new instrument and changed my mouthpiece accordingly. I believe a carbon fiber saxophone ligature like this has never been listed on Mercari before. It's that rare. From the official website: "It combines extremely high rigidity due to the carbon fiber, and its light weight does not impede the vibration of the reed, purely fulfilling the role of the ligature, which is to secure the reed. The high rigidity suppresses loss due to unnecessary resonance and transmits acoustic energy in an optimal state. The best reach, easy-to-use attack and articulation. It's a completely new concept ligature that allows you to obtain the natural vibration of the reed, as if the ligature doesn't exist. The tightening screw uses Vandoren's unique double-track screw to hold the reed with uniform force. The stainless steel tightening screw and the titanium screw receiver maintain the tightening of the ligature once set, preventing slippage during performance. *The carbon ligature is designed exclusively for Vandoren mouthpieces." However, it can of course be used with mouthpieces other than Vandoren. Thank you. [Reference Price] 103,400 yen
