I was just seen some guitars and the S models from ibanez really catch my eyes, specially the S770FM and then i found the S570. The only difference between this two guitars i that the S770FM has a flamed maple top and the S570 not.

The flamed top has any effect on the guitar besides the esthetic part???

it will probs have some effect that you would have to be a tone lord to hear, so its just looks
