The Yamaha YCLCXA Custom Pro A Clarinet features a grenadilla body and silver-plated nickel silver keys. Each tone hole is hand-tapered and undercut for optimum tone quality response and intonation. Made from the same grenadilla wood as the body the inset tone holes are hand-adjusted to achieve the most precise fit possible for a clearer more focused sound. The YCLCXA Custom Pro Clarinet comes equipped with a mouthpiece so players have everything they need to get started straight away. Please note that wooden instruments are affected by humidity and temperature and as a result the wood may expand and contract which would affect joints such as the tenons and bell rings. If you do experience any difficulties please feel free to contact us and we will be happy to help.
