Man, I don't know what it is, but my guitar keeps going out of tune, I didn't notice it this bad before. It's an Ibanez RG prestige, it's not old. Few full bends, and it's out of tune, some trem work, and it's way out of tune, the strings have been on it for 6 days now, well played in. I've never done any major kind of maintenence to the guitar since I have had it though, but I have never noticed it this bad. I don't know whats wrong with it
