The RT-48+ has a heavier shell compared to the RT-48. This gives it stronger projection and a darker sound. Response is very stable and benefits both the low and high Register.
Formerly named Perantucci mouthpieces, this Robert Tucci mouthpiece is a very popular size. The RT-48+ is based on the classic Helleberg concept yet wider than standard mouthpieces. The rim is enhanced for quick response and clarity. The sound is dark with a broad core. Excellent for medium-large and large-bore CC and BBb tubas.
