Bach Trumpet Mouthpiece 5C Rhodium plating has been applied with additional processing. Mouthpiece list price: 12,100 yen + Rhodium plating specification: 10,000 yen Total: 22,100 yen product! In my personal opinion, the tone is more powerful and forceful than a standard 5C. Used about 3 times and stored at home. I selected this mouthpiece from many others, so it's very easy to play, but I'm selling it because I have another mouthpiece I'm interested in. Rhodium-plated mouthpieces are rare and hard to find on the market! This is a highly recommended item, first come, first served! Below, manufacturer's quote: ↓ Bach mouthpieces are the most widely used by professionals and beginners around the world. They improve poor instruments and make good instruments even better.
