I'm rebuilding a 70's (or late sixties) Conrad Bass. Essentially I am de-fretting it and fixing the tuner and tone knobs. My Question concerns the neck. There is a slight curve to the neck. If placed fretboard down on a flat surface there is a slight gap towards the middle (around frets 7/10). I know the nut on top of the neck keeps everything straight. My question is: Which way do I turn the nut the straighten the neck out? Also, since the neck is off the body for the moment, how will I know how far to straigten it? Once the whole is pieced back together won't the strings start pulling the neck too?
