Ibanez RG 1570 won't stay in tune
I bought this used Ibanez RG 1570 Prestige, and I was pretty excited because it has the edge pro trem and decent pickups it's made in Japan and overall its seemed to be a pretty good guitar.
But It won't stay in tune at all. I've spend 100$ on professional adjustment, the bridge is parallel to the body, the springs are in great condition and the strings are not very old and nothing should be wrong. I also gave it some heavy trem exercise. (pulling the trem all the way back and forth a million times). But still it won't stay in tune.
I know that I'm not the only one having this problem with the RG 1570.. Is it really worth the money? I am so disappointed about this guitar. I can't use for concerts, rehearsal room, not even for practice.. It is useless :-(
Any help would be appriciated
