Rieger & Gräf 25 Tuba Mouthpiece This is 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. I tested it when I purchased it from a musical instrument store in Germany, and since then I have not used it until today after cleaning and disinfecting it, so it is in almost new condition. #Tuba #Tuba #Tuba Mouthpiece
