Leblanc’s Concerto is often compared to the Buffet R13. Side by side, the Concerto typically has a bigger shape of sound, with more lows than highs in the foundation. This one was owned and maintained by a professional player/repair tech. Features silver plated keys, multiple barrels. The wood and plating are in excellent condition. This clarinet is newer and in better shape than most A clarinets in the same price range.
