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 stock SG is silver plated and can be purchased in gold by special order. Please note that gold mouthpieces cannot be returned because they scratch so easily, so we encourage you to try it first in silver. Mouthpieces with a gold rim and silver outside can be returned if the gold shows no scratches. 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.
ID: 1.30 inches at .05 inches into the cup (33.02 mm)
0D: 1.90 inches (48.26 mm)
Throat: .325 inches (8.26 mm)
I am so pleased to have come across the Wedge mouthpiece, and to have purchased one for my sousaphone. The Wedge mouthpiece has improved my tones, my range, my "reliability" for hitting the note intended, and I think the agility for reliably hitting the desired notes even through upbeat tempos. A friend recommended that I get in touch with Dr. Dave, and the process of selecting just the right new mouthpiece was fun in itself. I also appreciated the patience that Dave exhibited to help ensure that I would select a mouthpiece that would be immediately and noticeably beneficial to my musical expression, and to have lasting attributes!
