The Laskey 30G tuba mouthpiece has truly become a game changer for 5/4 and 6/4 tubas. Scott Laskey designed the rim, cup, and exterior to solve many problems that tuba players face. The 30G helps the tubist achieve a full orchestral sound on a large instrument without sacrificing clear articulations or volume. The 30G has proven to be very popular as a medium-large mouthpiece for the modern large tuba.
The "G" stands for Geib that describes the medium deep bowl shape cup of the 30G mouthpiece which often pairs well with rotary tubas.
