Hi, I just recently noticed that my two Fender Precision show a visible deviation in the way the contours/body shapings are cut. One of them seems to be much thicker (One is an S8 the other an S9 serial-number, which places them both in the late 70s; or the early 80s for the S9-one). I generally have no trouble with that. I was just wondering whether such deviations were 'normal'. Here they are. I don't know if you can see it that well. The reflections on the upper one should help.
