Got my neck all ready to dress the frets. Having put a straight edge a cross it, I've noticed it has a very slight back bend in it. Like 1mm from end of the board to the other. I'm guessing string tension will more than fix that. I'm wondering whether to adjust the TR up a little (double acting) to bring it up close to straight before flattening the frets down, or leaving it back bent and going from there. What would y'all suggest?
