Custom hand-forged ligature for tenor saxophone rubber mouthpieces, top-tightening type. Ligature body material: Red brass (solid). Versatile. Shaft screw: SUS 304 (high-quality stainless steel), knurled knob of the tightening tool (booster structure): Yellow brass with nickel plating for rust prevention and increased strength. This versatile ligature can be used with standard tenor saxophone rubber mouthpieces to slightly thicker rubber mouthpieces. Photo upload: Mounting photos = Gottsu vi and a slightly thicker KEN OKUTSU mouthpiece mounting example. ・・・・・☆ The listing is for the ligature only. This custom ligature (top-tightening only) is handmade using hand-forging of red brass. The top-tightening structure is adopted for tenor saxophone rubber mouthpieces, and even if the mouthpiece size is slightly different, it can be firmly tightened with the knurling (nickel-plated brass: rust prevention and strength improvement), and this structure acts as a booster. (Versatile. Excluding some exceptional mouthpiece shapes) About "hand-forging". Hand-forging is a technique of forming three-dimensional objects by hammering metal plates such as iron, silver, and copper. Metals "sound better!" when hand-forged! This ligature for sale is made by refining copper, annealing it at around 400°C, and hand-forging it, so the hardness is higher, and it resonates richly from the low to high ranges. Original stamp: & SAX (shown in the photo) The part where the heel of the mouthpiece reed contacts is made the hardest, and the upper part is made elastic to increase versatility. In addition, the hammer marks of hand-forging have a deep flavor and a sense of luxury, and the hammer marks further improve the acoustic effect. The ligature has four points of contact or only the sides of the contact surface with the mouthpiece and reed, and the fewer the contact points, the better the acoustics. By attaching it and minimizing the tightening of the mouthpiece and reed, all the vibrations of the reed are converted into sound, improving the resonance. And the knurling of the tightening structure acts as a booster to boost the resonance, and the flow of breath is smooth, improving the sound cohesion. The knurled knob is on the right side when you put the mouthpiece in your mouth. From the product description
