This item is made of SV950 solid silver with 24-karat gold plating. Simply adding it to your everyday strap will provide the thickness and brilliance of sterling silver, along with the mellow quality of gold plating. Personally, I believe it has noticeable effects such as thickening the mid-range, softening harsh high frequencies, increasing the initial velocity and sustain of low frequencies, and bringing the sound quality of the flageolet closer to the normal range. I was using it attached to a saxophone holder, but I am selling it because I have replaced my instrument and am considering the overall balance. Thank you very much. [Reference Price] 18,700 yen
