Thank you for viewing. B. Tilz M8 tuba mouthpiece from the German mouthpiece maker B. Tilz. This mouthpiece is for B♭ or C tubas, but it has a large inner diameter, a shallow cup, and a small throat, so it is often used for F tubas. When used on a B♭ tuba, it produces a bright sound, but I think it will sound hard. It is used, so there are some minor scratches, but no noticeable large scratches or dents. There are no dents on the shank either. Thank you for your consideration.
