The Royal Global Polaris clarinet features a unique poly-cylindrical bore design that offers a warm, resonant, colorful sound and responsive feel throughout all registers. Silver plated keys, gold plated posts, alternate Eb/Ab lever, and two grenadilla barrels in 65mm and 66mm come standard on Polaris model clarinets. Manufactured from premium, naturally aged grenadilla wood, the Polaris clarinet will feel like home for those who prefer some of the more widely used "French" bore clarinets but with superior intonation.
