I will definitely agree that the Korean-made RGs are a hit and miss type of thing. I swear that every one that I've played has been a little different...especially with the neck. I lucked out in that my RG370DX has a PERFECT neck on par with a prestige neck while my RG321 has an alright neck but it definitely isn't EXACTLY the same. I've also played many other Korean RGs in music stores and they have this same problem in that they aren't all the same. So if you're going to buy one, I would suggest doing so from a store instead of online so that you can visually inspect the guitar.
I thought I was the only one who has problem with korean necks.
In the past, I owned RG 270DX from 2000, RGR 220DX from 01, RGR 320DX from 02, RG 320DXQM from 04.
the last one 320DX QM is special made for guitar center.
guess what? none of them has same neck.
for example, the 270DX feels a little bit thicker than 220.
RGR320DX has more like C shape neck.
And still the catalogue says that they are all WIZARD II... and made from the same factory CORT korea.
this is weird, but true...
