No point to fit an OFR into your Ibanez. You're better off buying a new guitar.

WD40?

actually, if TS wants a cheap solution, can try to find 2nd hand Schaller's Licensed FR on ebay. I'm not sure they still make them though but it's still pretty decent.

But then, what's the point of upgrading that Ibanez.

I'd say, save up a little more, get the Schecter C-1 Hellraiser FR (with Ori FR). That guitar is seriously worth way much more than it's price tag.

I think it's around USD800 so in RM will be 3k give or take.

but that guitar seriously blows away my own PRS Hate to admit it but it's true.

RR3 is about the same price but....

RR3 has lousier Pickups (SD JB/Jazz I think) compared to the Emgs 81/89 on the Schecter
RR3 is only using a License FR whereas that Schecter is using Original FR.
Plus, I don't quite like the RR3's tone. Tested one years ago and can still remember. But the Schecter totally blew me off.
Schecter comes with 24 frets
