This is a long comment. Regarding the metronome I'm using, the bell sound gradually became quieter and eventually disappeared. I asked the place that maintains my instruments to adjust it, but they said they couldn't. I had no choice but to buy a new one. Fortunately, I was able to purchase a very good one. However, even though I could hear the beat, I couldn't hear the "ding" sound for each measure. It was hard to believe that both were broken, so I investigated and found out that I had a problem with my hearing. It took quite a while. I had gradually developed high-frequency hearing loss. I don't usually wear hearing aids, but just in case, I put them on and could hear very well, which surprised and embarrassed me. So, I don't need the second one, so I'm putting the newly purchased one up for sale. I will continue to use the old one with hearing aids as before. Regarding the sale, I measured the operating time of the metronome. I hope this will be helpful. ♩=40 / Over 2 hours ♩=104 / 57 minutes ♩=208 / 28 minutes As stated above. I think the appearance is also beautiful. If you look closely, there is a small stain on the corner near the bottom. I will try to take easy-to-see photos, so please ask any questions you may have before bidding.
