Re: RS530 questions
Any type of Floyd tremolo will require MAJOR surgery, assuming the guitar had a Pro Rocker variant trem on it originally. The posts are too far apart, the trem route is much larger, but still not routed enough in some areas. The posts are the biggest detractor. Once pulled, the new FR style tremolo won't even completely cover the old holes. Any cracking in the finish while pulling the posts and you are ruined. It will show for the whole world to see.
I've done ONE in my lifetime, and I'm happy with the way it came out, but wound't do another. It's too much like brain surgery getting those posts out. Then, I recessed the trem, so you're routing across the very edge of a filled hole, into body wood. If it has a Rocker style trem stick with it, and lube the fulcrum points. If you need a trem I've got a gold one from the conversion I did.
