Thank you for viewing! This is a Perantucci Pt-88! I'm selling it because I bought a new mouthpiece and no longer have the opportunity to play this one. I purchased it in March 2024. There is no peeling of the plating or distortion of the shank, so I think it's in good condition. It comes with the original box. The following is a quote from the website: ◾︎Cup Characteristics Diameter: 33.5mm, large and deep hemispherical shape with a very rounded bottom. ◾︎Rim Characteristics Width: 7.0mm, rounded inner and outer rims. ◾︎Throat Bore Diameter: 8.1mm The PT88 model was originally designed for the low register. However, it was found to be suitable for medium-large and large-bore CC tubas. It works well with any CC or BB♭ tuba, producing a strong sound with a lot of volume. Recommended for advanced players. Instant purchase is OK.
