● Product Name ZEN-ON Zen-on Bass Recorder 5500B (Key in poor condition) Made in Japan Instrument ● Condition Generally in very good condition, it appears to have been handled with care or hardly used at all. There are two small dents, as confirmed by us. (Please check images 6 and 7) In addition, there is slight rust on the metal fittings, but it is relatively clean. However, the edge of the round part that presses the key hole is heavily rusted in one place. (See image 9) The reason for the defect is that the spring of the heavily rusted key is bent forward (perhaps caught on something and pulled forward?), and the tension is lost, causing the key to be loose. (I apologize for the unclear explanation. Please also refer to images 10-12) The spring itself is flexible, so it seems like it could be repaired by pushing it back slowly, but I am an amateur, and I think it's better not to touch it, so I will sell it as is. Other than that, I think it is a beautiful, good-quality item. I have checked the operation and performed a simple cleaning. I do not know the detailed handling or correct playing method of this instrument, but it produced a good low-pitched sound. Although there is a defect, it is in very good condition, so I would like to sell it to someone who can make good use of it. If you have any questions, I will answer them to the best of my ability, so please feel free to ask. ※ Important Notice ※ Recently, there have been some troubles in transactions on Mercari, etc. As I am an amateur regarding this instrument, it is possible that I may not recognize a fatal defect from the user's point of view. (For example, an amateur guitarist listing a guitar and not realizing the neck is warped and listing it as a good product) Therefore, please check the images carefully, and if you have any questions or things you want to confirm, please let me know, and please purchase after you are satisfied. Please understand that returns are not accepted after purchase (from the perspective of preventing switching, false claims, and other malicious claims). I hope we can have a pleasant transaction with each other, so thank you very much. ● Accessories Hard case, joint grease, etc., as shown in the images. There is no strap.
