Rieger & Gräf 25 Tuba Mouthpiece A tuba mouthpiece made by an Austrian alphorn maker. It is made of maple and the surface is protected with a varnish coating. It produces a unique, soft sound. It is almost the same size as an old Bach 25. It has a shank equivalent to an American shank. Since I tested it when I purchased it at a musical instrument store in Germany, and then cleaned and disinfected it, I haven't used it until today, so it's in almost new condition. #Tuba #Tuba #TubaMouthpiece
