This is a Yamaha student model (mid-range). Recommended for beginners. It has a silver head joint, an E mechanism that makes the third octave E easier to play, and a silver-plated finish, allowing for a soft tone. Overall, it's in relatively good condition, but there are some plating imperfections (small bumps) in places on the main body. I don't think it's very noticeable. The case is also in good condition. For this listing, it has been completely disassembled, defective parts have been replaced, and it has been readjusted. There are no problems with the sound. You can use it immediately. ◎ We are waiting for your comments regarding price requests and inquiries. ◎ Even during comments, we will give priority to those who complete the purchase process quickly according to Mercari's rules. ◎ If you wish to use anonymous shipping, please comment, and we will change it immediately.
