Re: Floyd Rose Question
The Original Edge's on the RG550s aren't exactly lo-profile afaik. They look a tad more refined than the OFR, but still have the whale's tail (which is a good thing for me, I prefer having the whale's tail). Manufactured by Gotoh, I like these ones, I personally reckon they're one of the few licensed Floyds that can just about hold up to the originals. I prefer the feel of the Original's myself, but the Edge should do you just fine, especially since it has those locking studs (great idea, pity they do not fit on OFRs I've been told, and bigger pity that Ibanez has discontinued this idea to save 2c on each guitar with the Edge Pro trems that came out '03) They definitely beat the hell outta the licensed trems found on most budget Korean axes, and I find them to be much better than the craploads of Takeuchi manufactured el cheapo trems (Ibanez Lo-TRS, Jackson JT-580, etc)
If you REALLY want an OFR, it'll fit right into the trem cavity, but I've been told that the locking studs will not physically work with an OFR; can't remember what the problem was, but it was something to do with the dimensions of either the knife edge or the post itself. If this is true, you'll have to pull the posts and install OFR compatible ones. Visually, the OFR won't be half as pretty, as the wings on the trem are assymetrical, whereas the wings on the Edge are symetrical, so an OFR in an Edge rout would leave you with a nice hunk of rout showing beside the bass wing. Doesn't bother me a single bit on my RG470, which was routed for a Lo-TRaSh trem, as the OFR plays 100x better, but when the Edge Pro plays so nicely already, why make an issue out of it?!
The Edge's are known to have knife edge and trem post manufacturing quality slips somewhere around '00-'01, where both items were made too blunt (i believe) to work well. The knife edges can be filed (if you have the balls

) whereas the posts may need to be replaced if tuning is an issue. ibanezrules.com used to have proper posts that were stocked after they fixed the quality issues, but I'm not sure if they still have any leftover. This may or may not be an issue with the 550, depending on when it was produced, and how hard you use the trem.
Just my $.02 Can't wait for Zerb's Floyd setup tutorial
