The Robert Tucci RT-83 tuba mouthpiece is based on the classic Helleberg design, but modified for modern tuba players and modern musicians! The RT-83 combines the right resistance to create an "easy" feel when complemented with BBb and CC tubas. The medium depth cup combined with a small/medium inner diameter leads to precision in the articulations. This combination also produces a full sound.
