So, I bought a really cheap Stagg bass guitar to mod it and before I started leveling frets, I realized the neck is bowed forwards when the truss rod is in relaxed state. I took it off a guitar 7 days ago, it's still bowed. What should I do about it? 1) Remove the frets and plane the fingerboard (the bow is 1-2mm at max) (this might also have a + of letting me reset the radius to my desired radius) 2) Leave it the way it is, and level the frets in as flat of a state as I can get it by tightening the truss rod 3) Something else? As for nature of the bow - it seems like a very natural, uniform bow - the neck doesn't seem to be twisted or warped, it just seems like it deformed plastically due to the truss rod stress. Guess the neck wood isn't the strongest, but I won't complain about it since I got the whole guitar for $50 to play around with.
