Yamaha SJ-1890 Yamaha SJ-180 acoustic guitar. The SJ-180 was made from 1981 to 1985. It is at least 30 years old, but you could not tell from the looks of it. The neck joint is solid and neck is straight, bridge is solid and there is no warping or cracking. Finish has a beautiful aged honey color and it has the warm Yamaha tone you would expect from a 30 year old guitar. Plays very well and the intonation is accurate. It has a slightly smaller body, just smaller than a dreadnought. The bottom bout width is 15 1/2 inches, the waist is 9 3/4 inches and the top bout width is is 11 1/2 inches. Please view photos...
