The Gen 2 31H is slightly larger than a Conn or Schilke Helleberg. Wedge H mouthpieces have 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.
The Gen 2 mouthpieces have a second generation Wedge design that incorporates elements from our highly successful Gen 2 high brass rim. They have an accentuated oval rim shape that extends right down to the base of the cup. This unique oval cup shape amplifies the effect of the Wedge rim, providing greater responsiveness and more core to the sound compared to a conventional round cup of similar depth and volume.
ID: 1.31 inches at .05 inches into the cup (33.27 mm)
OD: 1.91 inches (48.51 mm)
Throat: .325 inches (8.26 mm)
