This is a Yamaha student model. Recommended for beginners. It has an E mechanism that makes the third octave E (mi) easier to play. Overall, it's in good condition, but there are some minor scratches from use. I don't think they're very noticeable. The case is from another company, but it's almost new. For this listing, I disassembled the entire instrument, replaced any defective parts, and made final adjustments. There are no issues with the sound. You can use it right away. ◎ We welcome your comments regarding price requests and inquiries. ◎ Even during comments, we will prioritize the person who completes the purchase process first, according to Mercari's rules. ◎ If you would like anonymous shipping, please leave a comment, and I will change it immediately.
