to be honest i've never found yet a really BAD ibanez. but i've got a couple of great ones... i've bough exactly the same RGA121, used as well... it's the guitar i wish to put a C-bomb into these days!
mine is much better than my RG321, that's a very respectable guitar too... the only thing they've got in common is the shape, thoug... different woods, different neck and mechanics.
i MUST find a different bridge for the RG321, anyway... the damn screws keep scratching my hand and after a while it hurts, expecially if you're playing fast rhythms!
