This is a JY-45, a J-45 model made by K. Yairi. It's an all-solid wood acoustic-electric guitar. The preamp is working perfectly. TOP: Solid Spruce BACK/SIDES: Solid Mahogany NECK: Mahogany FINGERBOARD: Rosewood BRIDGE: Rosewood I am the second owner, so I don't know the detailed order specifications, but it has a cutaway. The high positions are easy to play. The sound gives a typical Yairi feel, with a jangly character. String height at the 12th fret (standard tuning): 1st string: Approximately 2.3mm 6th string: Approximately 2.7mm There are no noticeable scratches, but there is a white scratch near the 2nd string tuner on the headstock. Please check the photos. Comes with the original hard case. Other accessories are also included, please check the photos. Please understand that this is a used item before purchasing.
