Just curious as to how you know this?
I've taken a ruler and measured a Legacy One body against an RG3120 and RG8520. The two real Ibanez bodies had the same dimensions, which coincidentally conformed identically with the published Jem specs. The neck pocket on the Legacy One body was 3mm too short, which will cause the neck to sit up just like in this thread. Take a look at a bunch of the other recent build threads since Legacy One bodies have become commonplace, you'll see the same thing.
The 3 other bodies i have here have between 17 and 18 mm pockets. If your talking 1 or 2 mm, you dont have to re route the neck pocket. If anything, you would shave off a mm on the neck like i suggested. Since were talking about both an aftermarket neck and body, there are always tweaks involved in the process. The only solution is NOT having the neck pocket re routed...
If you think about it, it's extremely sad that a supposedly CNC'd part can't continuously conform to exactly the same spec. Think about that one. The bodies should be identical every time. Ibanez bodies and necks are 100% identical every time. That's what a CNC mill is designed to do.
Regarding hand sanding, i do sand the ENTIRE body when i get it. Thats alot of work in itself. Legacy didnt claim there bodies were final sanded anyway, so im not sure what you are talking about.
I meant Legacy One, not you. The reason I pointed it out is that I see a lot of bodies that have gone through the process of being painted that never had the AANJ shaped correctly. I've even been seeing this on Herc Fede's stuff. Kind of sad, really.
I, and many oher people have build guitars out of these bodies with no problem...
"No problems" is a really relative term. It's a block of wood, what can really be wrong with it? You can still build a guitar that plays perfectly fine, it just won't be dimensionally accurate to the design it's supposed to be copying.
I'm just saying you may want to consider switching suppliers for your bodies to someone who makes them dimensionally accurate. The bodies I'm seen from Sims look right on (saying nothing of potential issues buying frmo him) and Jaden Rose's bodies look spot on.
