Plus, some woods are more stable than others. For instance, bird's eye maple looks really nice, but its not good for necks(okay for a fret board). Quarter-sawn is better than flat-sawn as well. One problem is that old growth trees are harder to find so guitar makers are using more green lumber. If the wood is not dried and seasoned enough, it can
warp. The truss rod is installed to help offset the tension of the strings. A gentle warp that is even on both sides(both E strings) can usually be fixed by adjusting the truss rod. When the neck twists, then the truss rod won't fix it. I find the Ibanez Prestige necks that are 3 pieces seem to be more stable than the one-piece necks.
