SLIDE TONE / STARLING SILVER / For Horn, 5mm Changes the blowing feel and sound without taking away the instrument's individuality. Because it is attached to the slide tube, it does not scratch the surface. Gives the instrument even more resonance and a response that reacts to delicate expression. Also improves high-note accuracy and intonation. Your instrument is an important partner. You should love its individuality. That's why the absolute condition is not to take away its individuality. Not factory-pressed, but a handmade process like the instrument itself. A perfect balance of thickness and width that respects individuality while maximizing the degree of change. You should feel a different change than with weights or mouthpiece rings. By applying annealing, the molecules are made uniform, and the material is made to resonate more. By applying hammering, the material is brought closer to the state of the instrument itself. Please fine-tune the subtle changes with different sizes. 【YELLOW BRASS】 A metal (brass) used in many brass instruments, it has an excellent balance of sound, resistance, and strength. 【COPPER BRASS】 When a more lustrous and deep tone is desired, brass instruments achieve this by containing a large amount of copper in the brass. Instruments cannot be made with 100% copper to maintain strength. BUFFix is a parts item, so it uses 100% copper to achieve a lustrous and deep tone. The resistance is slightly stronger, and some people may find it harsh, but it is suitable for chamber music and other scenes where a wide range of sound is required. 【STARLING SILVER】 A material often used in straight-tube instruments such as trumpets, it is directional and characterized by its sound resonating straight and far. The resistance is not strong, and it is a material that allows you to dramatically feel the improvement in sound. Since it is a material that resonates far, you may not feel it much when you listen up close. However, it will definitely deliver the sound far away in a wide space such as a hall.
