Re: What is this RG ? 450 or 550?
Fuzzy pic but it looks like it has an Edge, so, it's an RG550. A Floyd would work, but unless the Edge is very badly worn or damaged, I couldn't think of a reason to swap it out.
There was an RG450, made in '95(not postive about '98, but it's definetly not in the '98 catalog- I have a copy of it right in front of me), that had a dot inlayed maple fretboard, though. If you could get a better pic, or find out for sure what the trem is, then you'd know for sure. A Floyd would also be a direct fit for it, as well.
There should be a sticker on the back of the headstock, thatsays what model it is. So, I don't know why he'd say it was a 450 if it's not... Hmmm... I need a nap!
