Bb clarinet - the new YCL-255 clarinets are the perfect start for young clarinet students. Made from durable ABS resin they are easy to handle and with the new adjustable thumb-rest and improved strap ring, they are now more comfortable to play. By removing the metal ring from the bell we have made the instrument even lighter yet it still remains very robust. Accurate intonation and immediate response help students to produce a round sound.
