Purviance 6⭐︎3B Purviance 6⭐︎3B This is the Purviance John Audino model. John Audino was the lead player on "The Tonight Show" for 20 years. The "B" in 6⭐︎3B refers to the shank size, which is compatible with instruments like Yamaha and Bach, and is equivalent to a Bob Reeves #5 shank. I purchased it directly from Bob Reeves in the United States, so the price is based on the current market value, but the new price was over approximately 50,000 yen. Please consider.
