// Harrison "ir" Ring // This is a new idea that fills the gap in the screw part of a conventional ligature with a special ring made of the same material. Can be used with existing Harrison ligatures. The vibration efficiency of the reed has been improved, while maintaining the full, brilliant sound of the Harrison ligature. It offers a different playing feel to existing models, with a solid feel and a clear, core-like tone. "ir" stands for idea ring. The size of the gap that will form in the screw part will vary depending on the mouthpiece or reed you use, so please use a ring of the appropriate width. *Please note that the ring has a diameter that is exclusive to Harrison ligatures and cannot be used with ligatures other than Harrison.■Specifications・Material: Brass・Finish: Gold plated ■Contents: 8-piece set of IR rings (2.0mm/2.5mm/3.0mm /3.5mm each 2 pieces) *Ligature and mouthpiece are not included.
