Up for purchase is a used Robert Tucci Sousapower 8 (SP8) Tuba and Sousaphone Mouthpiece in silver plate. Designed by master tubist Bob Tucci, the Sousapower series is world-renowned for combining heavy-shell construction with effortless open-blowing acoustics for maximum acoustic energy, projection, and register stability.
This mouthpiece is in good pre-owned condition with only light, normal signs of use, primarily light insertion marks on the shank from standard horn placement. The rim contour and cup remain smooth, clean, and comfortable, and the shank is straight and round. It has been thoroughly cleaned, sanitized, and prepared for its next owner.
BASED ON THE FAMOUS RT-88 / PT-88 The Sousapower 8 is built directly on the rim and cup geometry of the world-famous Robert Tucci RT-88 (formerly PT-88) tuba mouthpiece, but enhanced with a heavy-shell exterior mass:
Proven RT-88 Profile: Features the wide 33.50 mm cup diameter and deep bowl cup that made the RT-88 an industry standard for producing a massive, dark, and resonant sound.
Heavy-Shell Power: The added mass locks in slotting and amplifies energy transmission, giving you extra projection and dynamic range without choking or straining your air.
AMAZING OPTION FOR CONCERT TUBA & SOUSAPHONE Thanks to its unique balance of large cup volume and heavy exterior mass, the Sousapower 8 is an incredible choice whether you are playing in a concert hall or on the field:
For BBb and CC Concert Tubas: Delivers a deep, dark, and sonorous fundamental tone that anchors large-bore concert tubas with rock-solid low-register response and stability.
For Sousaphone & Marching Tuba: Cuts through outdoor noise effortlessly, giving sousaphone players a powerful, room-filling sound and unmatched projection.
