Ibanez Saber 540S 1987 Desert Sun Yellow

I have a mostly original 1987 540S Desert Yellow Sun for sale. Plays well but a little buzzy for my taste, but you set it up the way you want it, there is a tiny bit of relief in the neck so you could straighten it out some and make it flat as a board. It does have the original trem back stop, we all know those go for about $180-$200 alone... Pretty sure the tremelo bar, pickup ring, humbucker pickup, and case are not original to this guitar. Although the molded case does have the IBANEZ molded into it, I don't think it is era correct, but I could be wrong. Haven't taken the pickup out to see what it is, but it looks to be a Dimarzio X2N, I also can't be sure the pots are original either. The body has a long scratch on the backside, but most of the body is fairly clean, a few dings here and there but certainly not bad at all given it's age. The case is missing a latch, but will protect it well enough though it looks beat. The frets have a ton of life left in them, they look to be the original from IBANEZ so I don't think this was played a lot.
