This is a YAMAHA SG1000, a representative of Japanese vintage guitars. Based on the serial number, it is estimated to be from 1980. This is a rare guitar that is rarely seen, and I think it would be an ultra-rare model if it is in working condition. Although I am a layman, there are no noticeable scratches or noise, and you can use it without any problems for playing. Only one volume knob spins freely, but the other volume knob works, so there is no problem with playing. Please have it maintained if you are concerned. Please check the condition in the images as this is a used item, and consider purchasing it after you are satisfied. As it is from the era known as Japanese vintage, there is some wear and tear, but I think it is in good condition for a guitar over 40 years old. [Condition] Neck: Straight Frets: Plenty of room Electronics: No problems * Simple cleaning has also been done. Please adjust the pitch and string height to your liking. When shipping, we will carefully pack it with bubble wrap and cardboard. Due to the recommendation of Yamato Transport, we may loosen the strings slightly before shipping.
