The Robert Tucci Sousapower 5 is based on a RT best seller, the Robert Tucci 50+.  The SP5 has the same large diameter of the RT50+, but has increased wall thickness and a smaller shank.  The heavy weight of the mouthpiece gives it a tremendous amount of power that suits both the marching field and the concert hall!

Robert Tucci mouthpieces are designed to give the player the tools to make great music through a fantastic sound, full range of dynamics, and a quick response.  The Sousapower 5 continues this tradition because it's based on the RT50/50+, which has already proven to be a winner.
