The Wedge tuba mouthpiece line was developed with the assistance of Sasha Johnson of the National Ballet Orchestra of Canada. The SG is based on a Schilke Geib mouthpiece with slight modifications to the cup and a Wedge rim. It has a slightly more bowl shaped cup than the H2 and is designed to work especially well on rotary instruments. The SG retains a very similar feel to the Schilke, but provides improved core and clarity in the sound along with a more even response in all registers and better flexibility. The SG is available with the usual American shank or the larger European shank used on some larger instruments.
Wedge G mouthpieces have 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.
