Nagasawa Seisakusho Original Wind Instrument Boost Item Ligature Plate I purchased this the other day and tried it out today. I had it on for less than 5 minutes, so it's practically new! Ligature Plate Solid Silver For Tenor Saxophone ☆Purchased for ¥5,800. Below is the product information from Nagasawa Seisakusho: For reeds to produce good resonance and tone, the quality of the reed is greatly influenced by the hardness and maturity of the un-shaved, hard part of the cane (below the halfway point). It is said that the resonance changes as the reed's vibrations resonate and reflect off that hard cane part. By supplementing that part with a ligature plate, you can achieve better resonance, attack response, and a change in tone. By adding hammer shots to the silver material, we create variations in material hardness, thereby achieving a better response balance and resonance. As a feeling that perhaps only the maker can perceive, "You can feel a slight difference just by putting it on and biting down on the mouthpiece! Is it like a new reed?" I feel this way. Please try it. Material: Specially blended silver (50% silver content) Thickness: 0.25 mm Width: Made narrower than the width of the reed. It can be used with the ligature tightened in either direction. ★Typical features of surface finish★ Solid Silver: Characterized by the soft tone of silver. Nagasawa Seisakusho, in collaboration with a saxophone player who has won international competitions, develops and produces all-silver wind instrument boost items at their workshop in Hatoyama Town, Hiki District, Saitama Prefecture.
