■Suppresses harsh high-pitched overtones, achieving a clear, thick sound! The HDA thumb hook is an abbreviation for High Damping Alloy, and is a saxophone part made from "Alphe," a material well known for cello endpins. Wind instruments can increase the volume by transmitting and amplifying sound vibrations through the tube, but because the vibrations interfere with each other, the sound cannot be focused, resulting in a blurred, hard-to-hear sound no matter how loud it is. By installing this product, the characteristics of ALFE absorb noise such as minute resonances that are transmitted through the tube, It is possible to express the pure, original sound of the instrument as sound. ■Special alloy ALFE (Fe-8Al Alloy) Alfe, developed by Alfeco Co., Ltd., is an Fe-Al alloy with an Al content of 8% that is lightweight, has excellent magnetic properties and vibration damping, and also has heat resistance, making it an alloy that is expected to become a new material of the future (patented).■Specifications・Compatible models: Jupiter, Yamaha ・Material: Colored Alfe ・Finish: None *Please note that due to the nature of the product, small scratches may be present.
