Those Ibanez Sabers are the shit! I still have mine S540 from '93, pretty similar to yours!...
Yeah, a friend in a different band got one brand new in '89 and let me play it the day he got it and I've been in love with them ever since. My 91 (the Corvette Blue Me Away colored one) is my favorite guitar I've ever owned. Probably tell my wife to bury me with that one.
