The Buffet R13 Bb Vintage Professional Clarinet has one conical V2 66mm barrel and one cylindrical V. It has been crafted by Buffet with silver-plated keys, undercut toneholes, specially treated polycylindrical bore, and a silver-plated adjustable thumb rest. Crafted in high-quality unstained grenadilla wood to ensure evenness of tone and response. This is a clarinet that is reminiscent of the original '50s R13. Buffet includes a luxurious calfskin leather double pochette case with the R13 Professional Clarinet.
