Super cool Yamaha Dynamic Guitar No. 10, probably made in Japan in the early to mid '60s (1963 is an estimate). This guitar has that authentic, old-school, worn look, not created artificially but with actual years of playing: it has stood the test of time. Check the video I recorded while playing it: https://youtu.be/GaAiAYtpo1k It is comfortably playable and it has medium tension nylon strings. There are many imperfections, scratches and cracks, please check the photos carefully. It seems some issues have been repaired but I don't know how well. When I purchased this guitar it was already in this condition, so I don't know how the repairs were made, but I kept it because I loved the sound. The bridge is lifting and there are some detachments in the internal bracing, inside the body. However, I don't know how, this guitar still plays amazingly well in spite of these issues: it has a full, warm, round sound. It truly is magical how good it sounds. There is some slight buzz on the low strings, but nothing major. Please check the video and judge the sound for yourself, I'm only selling it because I'm decluttering my collection. This instrument is probably around 60 years old, so adjust your expectations accordingly. It has scratches, blemishes and imperfections. It will feel different compared to a new instrument. It is playable but it hasn't been professionally setup or repaired, so there are things that can be done to improve its playability. I'd suggest it to people who have some experience with vintage guitars and are willing to make adjustments down the line, or who can embrace the imperfections in exchange for a special sound and vibe.
