Yamaha trombone/euphonium mouthpiece. The shank is for large bore instruments. This is an old model, but it's new. There is no outer box, so only the mouthpiece itself will be provided. It has been stored without the outer box, so there may be small scratches or dullness, but these will not affect performance. (Please check the condition in the photos.) The specification is 【48】, which is considered a good size for beginners. This mouthpiece has a very well-balanced rim and cup with a narrow backbore. It has the ability to meet the advanced demands of professional musicians and is a highly complete mouthpiece. * Negotiations for price reduction are welcome. * Multiple purchases of this product are possible. We will consider a discount for multiple purchases, so please consult with us.
