I think I know the answer but looking for others to confirm or convince me otherwise. I have a gorgeous dark rosewood fretboard I want to use on a current build. Looks almost like ebony. However it is not flat. I have plenty of other boards I could substitute but none as nice looking and dark to compliment the body it is going on. At .25", it will lay flat if pressed and glued but I worry it it will cause problems for the neck (flame maple neck which also may not be the most stable wood compared to say quarter sawn plain maple). One could argue to position the fretboard bowed up and pressing in the frets could compensate for some of the curvature. I also plan to use a double action truss rod. A couple of pics are attached that hopefully capture the curvature. So should I go ahead and use it or is that just asking for problems?
