I bought this new two years ago. It shows some signs of use, but it's still relatively clean. There are no issues with playing it. It's a large mouthpiece, but it doesn't take too much breath, and I think it's relatively easier to play than other Warren Deck models. Quoted from the following site: A tuba mouthpiece based on the model of Warren Deck, former tuba player for the New York Philharmonic. Recommended for players who want to produce a thick and rich sound. Size: Inner rim diameter: 32.8mm Bore: 9.5mm Shank: American shank
