Re: Identifying an old RG. Need help!
Although Ive never seen a rgr520 before, especially a square heel, it seems legit. Just because its not in the catalog doesn't mean Ibanez didn't make it. The Japanese market gets all kinds of goodies most of us never see. But the serial is 90', it has an original edge trem, square heel, the pickups are actually v1,v2 not v7,v8 and fits for a 90 model. There is also the possibility it was a 570 that someone filled the center route and refinished the body. The body does look to be in great shape compared to the neck.
The neck has a split at the nut area and 1 of the nut bolts are missing, and there is alot of staining on the back of the neck from play. I couldn't really tell the condition of the frets from the pics but they are either most likely pretty worn or it has been refretted.
