First off, I agree that it is a feature which divides the JEM's from the RG's and is a reason why they've never done it before. Second, I believe they should do it to high-end J-custom RG's that are 1,000+$. And last, IT IS SO EASY TO DO I dont know why people mind doing it themselves. I'm a complete idoit and I did it to both my RG7 and AX7 and they came out perfect (thanks ryan). Im not saying you cant mess up...you sure as hell can. But anyone who is so picky and really wants the angle jack that bad I assume would be able to do it themselves.
But then again there are probably a lot of people who don't like the idea of having anyone else but a professional drill holes in their guitars. I didn't give a damn. if it still plays it plays. and better yet now I have these great angle jacks which were worth the effort. (and what very little it was) took all of 20 minutes to do both.
