I purchased this used instrument at a musical instrument store inside an AEON mall last year. I'm selling it because I don't use it much anymore. Manufacturing date: August 2018 Serial number: HO O 08 0037 I used it for about six months, so there are some small scratches, but no major scratches or dents. I haven't played it much, so there is no fret wear, and the fingerboard is clean. The whole instrument has a nice luster. No neck warping. How to check for warping: Press down on the 1st fret and the last fret, and the gap at the 12th fret is about 0.3mm (about the thickness of three Post-it notes). The standard value is 0.3 to 0.6 mm. Main Features and Evaluation: All Solid Wood: Solid wood is used for the top, back, and sides, and the sound becomes richer and deeper the more you play it. Sound Balance: It features a well-balanced sound from low to high frequencies and a clear tone. It is particularly praised for its "bright and clear sound." High Level of Completion: Traditional Spanish manufacturing techniques and Yamaha's research results are incorporated, making it a model suitable for upgrades by professional classical guitarists and intermediate players or above. Specifications Overview: ・Top: Spruce solid wood (spruce) ・Back and Sides: Indian Rosewood solid wood ・Fingerboard: Ebony Features: Bright and clear sound, warm and rich sound Playability: Efforts have been made to improve playability, such as thinning the finish on the back of the neck to transmit vibration energy throughout the guitar.
