Re: Ibanez SA560MB-ABT - can I fit a Floyd Rose?
Anything is possible with enough mods. But from a quick look at a pic of that guitar, it appears that the trem post spacing (that is, the width between the posts) is standard two-post trem spacing (56mm-ish) rather than Floyd spacing (74.3mm). You should check the measurements to verify those distances. That means you'd have to remove the old anchors, fill the old holes, and then redrill in the correct location for a Floyd. Additionally, you'd need to reroute the trem cavity. Those are pretty extensive mods best done by someone with experience.
I would be very reluctant to undertake something like that on a guitar with such a beautiful figured top, but that's just MHO. Similar conversions have been done plenty of times.
