Re: Just tried the RG 7321... and I HATED it
It really depends on the year, too. I won't pretend to be an expert on 7321 neck profiles or anything, but there's been a LOT of variability in Ibanez necks over the years.
The last few years, '06 and onward, say, Ibanez seems to be putting more or less the same neck profile on everything, a slightly tubbier-than-of-old D-shaped profile that reallly reminds me of the old 2027/CST necks, which I loved. Before that, the UV neck was a little more C-shaped for at least the '99-onward period, before that the super skinny old-style UV neck which is thinner than I generally like but comefortable nonetheless.
I don't believe I've ever played a '04 7321, but I remember an '06 I played at a GC that had a great neck, nice enough in shape (obviously the fretwork wasn't jawdropping, but was at least solid) that I almost bought the thing for a project guitar, and probably would have had I not been meeting a guy there to pick up a C7 Blackjack. It was nice and substantial without feeling bulky, with a sort of D-like profile reminisenct of my '07 1527 and the 2027's and CST's I used to own.
