I take all their neck shapes with a grain of salt. I've had many different rg's, j-custom's and even an original first model k-7 before and whether they are supposed to have different or even the same necks they are always one of two profiles, a thinner one that's flatter in the middle with wider shoulders, or the fatter in the middle one with non-intrusive smoothed over shoulders. Even the same model guitars with the same neck type have differed with one of these two shapes, ime.Not that I was going to buy one, but it's listed now with a Wizard 7 profile, and not k7, so kinda lost y all interest if that's correct.
- My point is that you might try one and it has the neck you like, or not, but they don't probably all have the same profile neck, even though they're supposed to. They probably have one of these two shapes like every other Ibanez I've played. So there's hope yet! Just make sure you play it in person or can return it or something. : )
