YAMAHA Yamaha Cornet YCR4330G Good Condition, Cleaned YAMAHA Yamaha Cornet YCR4330G For sale. I purchased this used in good condition and used it about 3-4 times a month for about 1-2 hours each time for about 3 years. Although it's a mid-level cornet, the gold brass is only available in this series, so it's recommended for those who want gold brass! Compared to the higher-grade 6330 yellow brass model, it felt like it produced a bright, expansive, and solid sound. By the way, the 6330 has a dark feel and no expansion, but it gave the impression of a thick, compact sound. It depends on your preference, but I can't say which is better, but if it suits your taste, it seems like a cost-effective instrument. There are small scratches, but no noticeable dents. Before listing, I cleaned the inside of the tubes with brass care, washed it with neutral detergent, polished it with silver polish, and applied oil and grease so that you can play it immediately upon arrival. If you wish, I will include a used 11E4 mouthpiece for free, so please let me know when you purchase. Below are a few custom modifications. ・Changed the 1st to 3rd piston felts to Klang brand after purchase (2 places on the lid and inside) ・Installed O-rings on the slide tubes ・Replaced the piston springs with new genuine ones ・Replaced the main tuning slide and 3rd slide water key corks with new ones Good condition, cleaned The piston felts were changed after purchase 3 years ago and have been used as is, but the O-rings, springs, and corks were newly replaced with new ones at the time of listing. The case is the original one, but I will send it in the pro model case that came with the 6330II. The case is used, but it can still be used. If you have any questions, please feel free to comment and I will answer them.
