I am the lead trumpet player in a big band, and the manufacturer recommended this to me as a type that "makes the core of the sound more solid and makes it easier to hit high notes." Manufacturer's Description: An alloy with a silver content of 92.5% is called silver 925. It is a material widely used in precious metal accessories and musical instruments. Among the silver 925, the metal produced with only copper for the remaining 7.5% is given the name sterling silver. Each metal has its own natural frequency (resonance frequency), and the damping behavior of vibration differs depending on the metal. In other words, each metal material has a frequency that resonates easily. STARLING SILVER resonates strongly over a wide range of frequencies, from high to low, resulting in a remarkably wide and deep resonance. By using sterling silver for the ring and bridge parts, a lot of vibrational energy is transferred to the instrument to maximize its potential. It has become the best finish in the Re:VIBRATION lineup. You may feel a slight increase in resistance, but the effect is "amazing." The 【HAMMERED】 model not only has a beautiful, irregular reflective pattern due to the hand-hammering process, but also hardens the metal. This transmits vibrational energy more effectively than the normal model. Hammering is a processing method also used in accessory engraving, such as rings. After hammering, polishing will remove the edges of the beautiful pattern. At our workshop, we perform hammering after polishing. Although the work process increases, it creates a beautiful hammered pattern that retains the edges. Because it is a hand-hammering process, the product you hold is a one-of-a-kind pattern in the world.
