TB community. I have a 2010 Fender American Standard Jazz and I love just about everything about it. I was having some intonation issues on it and just couldn't seem to get the setup right myself (I am by no means an expert with setups). So I took it into a local guy, whom I trust and he was looking it over. When he looked at it, he pointed out to me that the neck seemed to have a little issue that on the left side (looking from the head to the body) there seems to be a small downward dip between about the second and sixth or seventh fret. This freaked me out. He said it wasn't any big deal and that since no pieces of wood are exactly the same, these things happen and it's perfectly okay. He also proceeded to get the bass set up perfectly and the intonation perfect. I've had it for about a month since and still set up and intonation perfect. I just can't get this little neck issue out of my head. Is he right about this and it's "nothing to worry about" and it's pretty common with natural things like wooden necks? or will it eventually cause problems??? Help!
