Miraphone TU43 Tuba Mouthpiece I purchased this used, in unused condition. Specifications are as follows: TU43 Very Deep 33.0 mm (1.299 inch) 8.9 mm (0.350 inch) I bought this thinking it had similar specs to a Tilz WH-2 mouthpiece. It's a very good mouthpiece, but the shank didn't fit, so I'm selling it. It's large with a wide throat, but I think it's also easy to control (in my opinion). I'm selling it at a low price because I bought it used. I think it's a first-come, first-served deal, so if you want to try it, please do! Keywords: Tuba, mouthpiece, Miraphone, Tilz, WH-2
