I have a '91 RG770DX. From what I can find online, the violet wasn't released until 1992, but the serial number on mine dates it to 1991 (the serial is F157707). Its still got the stock pups and its a beauty. To get to the point, I am GASing for a new amp and bad. I don't know if I can part with her but I wanted to get an idea of how much shes worth if I do decide to. I'll post detailed pics as soon as I can get them off my camera. As far as I can tell everything is original. There is a small crack in the pick gaurd, very minor cosmetic damage (maybe 1 or 2 small scratches I'll try to photograph and 1 small chip), missing the back plate, and lost the stock strap buttons. I figure if I can get an accurate estimate anywhere online, it would be Jemsite. Thanks in advance to anyone who can help!
