Yamaha YAMAHA Trumpet Mouthpiece 12 Old Engraving This is an old-type Yamaha mouthpiece. While there are no major dents, there is some slight distortion and a thin dent on the shank. There are no other scratches or dents that would interfere with playing. This type of mouthpiece was manufactured during the period of technical collaboration between Yamaha and Schilke, a top-tier brass instrument manufacturer, from the late 1960s to the early 1980s, a period of about 10 years. These mouthpieces are now receiving higher evaluations than before. The "12" rim is about the size of a V. Bach 6C. Compared to the V. Bach 6C, it has a flatter and wider shape, providing a good feel on the lips. It has a shape that stabilizes the embouchure and makes it less tiring even during long phrases or long hours of hard playing.
