YAMAHA horn mouthpiece, model 30. - Brand: YAMAHA - Model: 30 - Type: Horn mouthpiece - Condition: Used - Material: Metal Thank you for viewing. This is an old-type French horn mouthpiece from Yamaha, model number "30," with a silver plate finish. The manufacturing and engraving seem to vary slightly depending on the production year, but the body has a precise engraving in a retro font that reads "YAMAHA JAPAN 30." This type of mouthpiece was manufactured during the era when Yamaha first started producing brass instruments, from around 1970 to the early 1980s, and it is a mouthpiece that is gaining more recognition than before. Unlike the precise but somewhat sterile mouthpieces produced by today's mainstream computer-controlled lathes, each of these has slight individual differences in a good way, making them excellent mouthpieces with a handmade feel and a sense of human touch.
