Re: Natural wood finish lightweight locking trem Ibanez models?
Generally speaking, if it has an Edge or Lo Pro youre good to go.
As far as a "short list" with features you want, this is pretty simple, check out 540S and RG570, the 540S has a natural oil finish one and a stained oil finish one; some have maple fretboards, others have rosewood. Personally, I think the maple looks out of place on these. The 570 has a number of various models, and frankly difficult to just give you model specific examples; but one example for sure would be RG570MH. I quite like those. There are also some japanese and european specific models, but they are more or less just variants of the rg570. (i.e. rg580, rg670, etc). One model to be careful of is the s470. Some are korean made with lower quality bits (still a decent guitar), and some are MIJ with proper edge trem and the lot. Id ask if youre not sure.
Good news though, if you shop smart, you can get BOTH of those for your "800-1000$" budget lol.
