Thank you for viewing. I am selling a mouthpiece that I no longer use. [Product] Trombone Mouthpiece W. Chr. Schmidt USA 5GS (Small Shank) *No box Retail price: 40,700 yen. Diameter: 25.50mm This is a German-made mouthpiece produced using the traditional "casting" method. It has an elegant, soft resonance and brilliance. It also has a fair amount of weight, so the sound is well-defined. It works well with small-bore models such as YAMAHA 8410 and 891, providing a sense of composure and coherence to the sound. As Schmidt mouthpieces themselves are not widely distributed, how about it if you are looking for one?
