This is a Yamaha student model. Recommended for beginners. It has an E mechanism, making the third octave E easier to play. It shows signs of use overall. Non-original parts have been used to repair any issues (parts that are not visible, and the - screws have been replaced with + screws). The case is also not the original. It can be used without any problems for producing sound. ◎ Please refrain from requesting a discount. The price has already been set low.
