Product Overview
The Gen 2 30G tuba mouthpiece is the same diameter than the Wedge SG or Schilke Geib. 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. This cup works especially well with rotary valve tubas.
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: 1.30 inches at .05 inches into the cup (33.02 mm)
OD: 1.90 inches (48.26 mm)
Throat: .325 inches (8.26 mm)
Material - These mouthpieces can be made in either Delrin or Acrylic plastic. Here is a comparison of their characteristics:
Delrin:
- Feels softer on the chops because it has more give than metal. This is a great advantage for players with braces.
- Not as slippery as silver, giving more grip.
- Added grip makes Delrin mouthpieces feel smaller than their metal counterparts with the same size designation.
- Not as smooth as metal, so some players may feel slight chop irritation for the first day or two while they adjust.
- More comfortable to play in cold weather because they feel warm on the chops.
- Plastic mouthpieces are more responsive than brass, making soft entries more secure.
- Articulation less crisp with less point at the front of the note compared to brass.
- Darker sound than brass.
- Less core in the sound compared to brass.
- Sounds darker than brass mouthpiece when used with brass or stainless steel backbore.
Acrylic:
- Feels softer than brass but less soft and Delrin on the chops.
- Less slippery than metal but more slippery than Delrin.
- Grip intermediate between Delrin and silver.
- Feel slightly smaller than the metal counterparts.
- Smoother than Delrin, very similar to silver.
- Comfortable to play in cold weather.
- Responsive to soft articulation.
- Articulation is clearer than Delrin, very similar to metal.
