I want to buy a Ibanez RGT6EXFX
can someone in this forum tell me if this guitar is a good guitar for metal like metallica, trivium and some more?
can someone describe the sound?

I remember a long time ago I used to want that guitar. Head.Banger, it's made of basswood. So no, I wouldn't recommend it at all. The neck is fast, but it's not gonna do you any good playing anything like Trivium. I think the only thing this guitar is good for is insane Mathgrind and shit.

If you still want an Ibanez, try the S620EXQFM.
