Product Overview
The Gen 2 28G tuba mouthpiece is similar in size and depth to the Bach 18 and Yamaha 67C4 tuba mouthpieces. It has a Gen 2 Wedge rim with an ID of 1.28 inches and an oval, Geib shaped medium deep cup, and a .325 inch throat.
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.
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.
