Re: Is the JEM body the same as the RG body?
There actually was an alder RG aswell, the RG570CT from around 1994/1995.
But yes, if you just want to saw out the rough body shape from a block of wood, the RG and Jem shapes are the same, and so you can use the same template. The basic pickup, electronics and hardware routings are also the same (assuming we're talking about a bolt-on neck H-S-H pickup RG with a scratchplate, as there are others).
It's mainly the details that are different (as mentioned, the lion's claw, the monkey grip, and the tilt jack on the JEM).
