Re: will a Rg neck fit and work on a saber body?
Okay this is getting off all wrong from the start. The first thing to establish is what neck joint you have (which can not be ascertained from "werd") LOL
If it's the AANJ then there's no point in trying. Fettouhi is right, they might fit in eachother's pocket, but the extra two frets make it a total waste of time.
If they BOTH are the old style neck joint, then absolutely it will work. But it would require you to saw off the last two frets (otherwise they'd crash into the neck pickup) AND you may have to shave down the underside of the fretboard. On an RG, the fretboard extension has extra wood from the neck under it. That was done to stabilize it, since it's a long extension. It would be more likely to curl and warp without it. If you cut it down to 22 frets you don't need that extra thickness. But more importantly, you can't have that extra thickness because the body isn't cut away for it like the RG's were. The fretboard might hit the guitar's top before the neck sits flush in the pocket. If that happens, you'll crack and lift the board off when you tighten the neck screws.
