This is a K. Yairi Nocturne. The sides and back are acacia wood, and the top is spruce. It's a solid-top (high-end model) with a list price of 89,900 yen. Comes with the original hard case. The sound is very warm, with a crisp and pleasant aftertaste. I was planning to install a pickup, but the acoustic sound was good enough, and I was satisfied, so it remains original. The strings are a bit worn, but I hope you'll replace them to your liking. (That's why it's priced lower) - Body Material: Spruce - Back Material: Acacia - Neck Material: Mahogany - Accessories: Hard case This is a highly recommended model for those who find full-size acoustic guitars difficult to hold but still want a high-quality acoustic guitar. It gives a much more resonant impression than recent Nocturne models. Please consider it. I've also adjusted the price. Please refrain from negotiations. Thank you very much.
