The guitar has been adjusted at a repair shop for a lower string height, making it easier to play. Quoted from the internet. The guitar is made of carbon, so it's easy to maintain. The sound quality is surprisingly rich and musical, defying the hard and inorganic image often associated with "carbon fiber." The secret lies in the uniquely developed three-layer "R.S.B. carbon fiber top." This top material efficiently transmits the string's vibrational energy to the air within the body, achieving a rich resonance comparable to that of a wooden guitar. When you actually listen to the sound, you'll find that the low frequencies are powerful without being muddy, the mid-range has warmth and body, and the high frequencies are brilliant and clear, demonstrating a very well-balanced tonal characteristic. Many reviews also praise it, with comments like "it resonates more than it looks like it would" and "the sustain is unique and pleasant," indicating its high acoustic performance. Due to the characteristics of carbon materials, the sound has a very fast attack, and each note sounds clear. This allows it to accommodate a wide range of playing styles, from delicate fingerpicking to powerful chord strumming. You can get sufficient volume without an amplifier, so it will perform well not only for practice at home but also for small acoustic live performances. While there is no "growth in resonance" due to aging, which is characteristic of wooden guitars, it will instead deliver peak performance from the day you buy it and continue to provide stable sound quality unaffected by condition. The original box, soft case, and hex wrench are included. It's a very beautiful item, almost unused, but since it's a used item, please refrain from purchasing if you are overly sensitive.
