Re: Ibanez RG 7420 - Neck question
I'm a little rusty and the black-on-lock makes it tough to say for sure, but I THINK that's a 7620, not a 7420. The New-7s in the 7620s had brass pickup tabs like this, vs black on the 7420s, and it's really tough to say for sure in the second picture but that looks like it's a LoPro Edge 7, not a LoTRS 7.
I used to own a 7620GN with a three peice neck just like that one - that doesn't really prove anything, though, as the 7420 and 7620 were both Japanese-made and used the same neck, which is why you see so many people selling "7420 with 7620 neck" guitars.
Either way, if that's priced at a fair price for a 7420, grab it. 7620s aren't quite as cheap as they used to be, but in the wake of their being blown out you could grab a stock one in a UV1000 case for like $4-450, which is obscene for how good a guitar they were; they were the best bang for your buck in the the Ibanez second hand market for ANY number of strings.
