This is a Yamaha student model, recommended for beginners. It features an E mechanism, making it easier to play the E in the third octave. Overall, there don't seem to be any problems, but it appears the previous owner didn't maintain it, and there is some slight clouding in places (removable with cleaning). Also, there are some minor scratches from use, but I don't think they're very noticeable. The case also shows some signs of use, but I don't think it's very noticeable. In this listing, I have completely disassembled it, replaced any faulty parts, and readjusted it. There are no issues with the sound. You can use it immediately. ◎ We welcome your comments regarding price requests and inquiries.
