Ok, so what do you guys do when you adjust your truss rod. Just to prevent any sarcastic comments, i know you adjust the nut at the top. My question is, how much, and what do you guys look for when you do it? My wife (in 2 months) is afraid that when im setting up my guitar, that ill crack the neck and throw $300 down the toilet. I didnt think it would be that hard, but i want to make her feel better about the whole thing.
