Yamaha Vintage Acoustic Guitar Model: FG800J Black Label Serial number unknown Sides and back are New Jacaranda The guitar itself is relatively heavy and has a substantial feel. The sides are likely plywood, and the back is probably solid wood, but due to the weight, it may be a laminated board. The neck and grip also feel thicker compared to others. There is no major damage to the body, and there are no noticeable cracks or splits, but there are some dullness, small scratches, and linear scratches on the sides, top, and back. The soundhole ring shows the wood due to wear from picking. From the waist on the 6th string side to the bottom, there are multiple linear scratches from surface cracks. The back plate also has quite a few white linear scratches, and along the binding on the 1st string side waist, there are surface cracks, and a slight step can be felt with a finger. None of these are damages that penetrate the inside, and they are not very noticeable, but there are surface cracks like weather checking that are difficult to see in the photos. Please refrain from purchasing if you are concerned. There is no major damage that would cause it to dent when pressed. 12th fret string height: 3mm+ on the 6th string side, 2mm on the 1st string side, which is slightly high. Therefore, the high frets may be difficult to play due to the thickness of the neck. Fret height is 70-80%, and there is plenty of it. Fingerboard: Ebony, dullness, and signs of use, but no cracks. No bridge lift. Nut width: 45mm. Saddle height: about 3-3.5mm. There is no noticeable deadening of sound or buzzing. Original pegs, rotation and tuning are not a problem. The top plate has a slight bulge under the bridge, and the back plate also has a slight bulge, but it is within acceptable limits. Neck condition: almost straight. Neck back: There are some capo marks. The rod is stiff, but it rotates left and right, and can be turned about 60 degrees in the tightening direction. The sound has a large volume, especially the bass has a booming impression, a powerful sound, and I think the sound is quite clear. Please note that it comes with an oversized Yamaha hard case of a different era in the photos. No returns or refunds. Will be shipped in bubble wrap and cardboard. We do not trade with Okinawa and remote islands. For those who understand the condition of the guitar.
