Perantucci Tuba Mouthpiece PT-63 Silver Plated
 
These mouthpieces are all new old stock and some include "Mr Tuba" stamped on the mouthpiece from the factory.
 
Perantucci say the following about this mouthpiece.
Model PT-63 combines the rim of the PT-89 with the cup of the PT-80. The cup diameter is slightly smaller than other popular F-tuba mouthpieces such as the PT-20, PT-64, PT-65, PT-72 or PT-80. The mouthpiece responds accurately in all ranges while providing excellent intonation, particularly on modern large-bore instruments. The sound full, dark in colour with a strong centre and excellent projection.
 
Cup: 32mm diam. Medium depth, well rounded at bottom 
Rim: Width 8mm. Well-rounded inner and outer edges 
Throat Bore: 8mm
Standard Large Shank for most European Models (recommended for most instruments)
 
Please note - For mouthpieces purchased online I am not able to offer trials - if you are looking to try this mouthpiece, please contact Mr Tuba at sales@mrtuba.com
 
These mouthpieces are all new stock.  They may have the odd mark on the shank where they have been inserted into an instrument in-store and the box maybe a little tatty, but they are all new stock.
 
I find mouthpieces impossible to take photographs of due to the reflections, so the image shown in the stock image from Perantucci.  I am happy to supply additional images if you send me a message.
