Yikes!!! That definitely isn't acceptable.
I fell into all the hype from youtube saying it was amazing.That definitely isn't acceptable, but every company can let sub-par ones slip through the cracks. It's not really shame on Ibanez, but on companies in general. You could have requested a replacement, and gotten something like one of 3Bolt79's two perfectly acceptable guitars, and been happy as pie again.
Good advice! I have my eyes set on either a standard RG or get my hands on a Prestige model again. I miss the stability of the 5 piece neck.
