This is a Yamaha student model (mid-range). Recommended for beginners. It has a silver head joint (with markings) and an E mechanism that makes the third octave E easier to play. It's silver-plated, producing a soft tone. Overall, it's in relatively good condition, but there is a slight plating defect (small bumps) on the foot joint (not noticeable in the photos). There are minor scratches from use, but I don't think they're a concern. The case is also in relatively good condition. For this listing, it has been completely disassembled, defective parts have been replaced, and it has been re-adjusted. There are no issues with sound production. You can use it immediately. ◎ We welcome your price requests and inquiries in the comments. ◎ Even during comments, we will give priority to the person who completes the purchase process first, according to Mercari's rules. ◎ For those who wish for anonymous shipping, please comment, and we will change it immediately.
