The Master CL20SK Ida Maria Grassi clarinet is an intermediate level instrument with a wood-look ABS body and bladder pads. The use of ABS guarantees easier emission, greater durability and resistance to humidity and temperature changes much higher than wood. The instrument has the Boehm system with 17 nickel plated keys. The adjustable thumb rest allows you to find the best thumb position. The instrument comes with 2 barrels of different lengths to help you find the best intonation. The clarinet is equipped with all the accessories for those starting to play: tuner, lettuno, case, drying cloth, mouthpiece and reed.
