Jerome Wiss, a French instrument maker, studied tuba and euphonium, and then gained experience in instrument repair and manufacturing, establishing a workshop.

R. Szentpali CB This model has a very large cup. Although the inner diameter of the rim is only 33.9mm, it is an ultra-large cup, but due to the effect of the gouging process, the actual width of the sound is wider than the JK 1AA with an inner rim diameter of 34.0mm, which is said to be the largest in history. Thanks to the good response of the rim, you won't feel an extremely large size, and it can be fully controlled by players who can use PT-88 etc. For B.C. tube Rim inner diameter 33.9mm Throat diameter = 8.2mm Deep V cup Shank American #Tuba #Tuba #Tuba #Mouthpiece
