Perantucci Tuba Mouthpiece PT-66 Silver Plated
 
These mouthpieces are all new stock and some also include "Mr Tuba" stamped on the mouthpiece from the factory.
 
Perantucci say the following about this mouthpiece.
Model PT-66 is a traditional, German-style mouthpiece giving a clear and lively sound. It's deeper cup provides more volume with a slightly mellower quality than model PT-64. It is highly recommended for the F and Eb tubas, but is also useful for the CC and BBb tubas where quick response and a clear, vibrant sound is desired.
 
Cup: 32.5mm diam. Medium depth, bowl-shaped 
Rim: Width 8mm. 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.
