Re: 1987 RG ??? Please help...
All I can say is that it's not the modern RG shape with the sharper cutaway horns introduced in 1987. This is the design that preceded the current one. This would be from 1985-early 1987. Ibanez has been known to make mid-year or "running" production changes so it's possible that this could be an '87 before the body design change.
I've seen guitars like this one from $200 (beater/used/swapped hardware and pickups) to $500 (great condition w/original parts). Good luck.
