Identical to the Yamaha 450, this used Yamaha Advantage 400AD clarinet is a well-made instrument with a great sound and a comfortable feel. There are no cracks in the wood body, and just a little roughness on the outside of one of the tenons. The logo, though faded, is visible on the top joint and bell. Two of the tenon corks, as well as the one on the mouthpiece, are new, and pads and springs have been replaced where needed. There is light plating wear, with cloudy areas on many of the keys. The mouthpiece, topped off by a leather inverted ligature, is discolored, and has several light scratches; however, it remains in very good playing condition. The model number is no longer visible, but there is a lyre on the front of it. It comes in an impact resistant Yamaha case that has a little scuffing on the exterior, while the plush interior shows cork grease remains and light wear. Included are a reed guard, cork grease and swab.
