Wedge Tuba Cups

F Cup: The Wedge F tuba cup is similar to a PT65 cup. Is has a shallow, modified V shape, which provides an excellent balance of clarity and projection with an even response in all registers and a round, full tone. 

G Cup: The Wedge G cup is a Geib style cup similar, to the Schilke Geib, Bach 7, Bach 12, and Yamaha 67C4 mouthpieces. The cup shape is a modified funnel, which is slightly more bowl shaped than a Helleberg style cup. The Geib cup sounds is less dark than a Helleberg cup, with a bit more projection. 

H Cup: The Wedge H cup is a Helleberg style cup similar to the Schilke Helleberg II, Conn Helleberg, and Laskey H series mouthpieces. The cup has a deep funnel shape, providing a dark, round sound that still has excellent projection when desired. 

D Cup: The Wedge D cup has a deep bowl shape similar to the PT50 and PT88 mouthpieces. The D cup with a smaller diameter is an excellent choice for a player looking for the characteristics of a Bach 24AW on EEb tuba. The D cup in the larger diameters produces a huge sound with a very even response in all registers.
