YAMAHA Yamaha Cornet Pro Model YCR6330Ⅱ For sale. I have used it with care, so while there are some minor scratches from use, there are no major scratches or dents. Before listing, I cleaned the entire instrument with brass care and greased it. After cleaning, I only played it for a test. [Customizations] ・Replaced the piston felts with Klang brand ones, both outer and inner. ・Replaced the piston springs with new genuine ones. ・Installed O-rings on the 1st and 3rd valve slides. The custom parts are still in good condition. I used this for regular concerts, so there are no issues with the sound, and there are no problems with playing. You can use it immediately upon arrival. The case in the picture will be used for shipping. The mouthpiece is used, but I will include a YAMAHA 11E4. I will answer any questions you may have, such as adding more pictures, as best as I can.
