Is this normal? I have a new 2018 Gibson Custom Historic 1960 les paul.I noticed that the neck heel on the back of the guitar looks a tiny bit crooked,as you look at the back of the body where the neck heel is.When i look at the headstock from the too,it looks like its very slightly twisted to the right as if the neck is mounted in the body that way? Is this normal practice.I just want some assurance that its ok honestly, it does seem like the heel is simply sanded a bit crooked,as i put a streight edge on it,the streightedge rocks a bit towards the right where you can see the gap get wider...but then it seems like the headstock is slightly following the heels angle.if i lay the guitar down,the right tuning machine hits the table first,leaving about a 1mm gap between the left tuner and the table,not a big deal,i think? Should a headstock be perfectly streight with the body? And should the neck be mounted in the body perfectly streight? Or is my situation normal? Thanks guys
