you said it leans in slightley? well, first, if you have ever done this before, get someone who knows what there doing, to adjust your truss rod. i can tell you havent since you are asking us. but if you dont want to take my advice, turn it counterclockwise very slightley, and play, do that untill its sounding good. and dont fuck it up.
and mr colored tape, dont be an idiot. the tape will severly hamper the sound of the guitar(or bass, in this senario) seeing as how it is a piece of highley absobent material, thats why they use metal.
