Yamaha - YCL221II Clarinet The YCL-221 bass clarinet boasts the pro-neck angle. The pro-neck angle is exclusive to this model and enables a more natural playing position. The matte finish ABS body on the YCL221 provides a better appearance by showing fewer handling marks, warmer sound, excellent response, and a lighter weight than a Grenadilla wood body. The position of the register tonehole is scientifically designed for extremely accurate intonation and the easy-to-assemble joint system and rounded key connector make this an ideal instrument for students. Yamaha is offering a matte finish ABS resin bass clarinet with a tone quality very close to that of a professional wood model. It’s the YCL221II, whose design is based on that of our professional YCL621II. This instrument boasts several important new features, including a neck angle similar to that of a soprano clarinet, and a unique joint connector which makes it easy to assemble the main body - thus permitting a compact case.
