Brand new 64mm barrel for Buffet RC Prestige A clarinet. Stamped on the back "PRT A64" (PRT is the designation for Prestige RC  clarinets).

This is a stock barrel for a RC Prestige clarinet. Use it on a regular RC  to improve tone, response and possibly tuning .

This barrel allows to tune to 440 Hz when ambient temperature is low, which is often the case in many venues during winter months. 

When the ambient temp. is 72F, after a warm-up the clarinet will tune to 442Hz. In warmer temps it may need to be pulled out by 1-1.5mm to tune to 440Hz.

Please check my feedback and bid with confidence!

Thank you for looking.
