On my Edwards SG, the neck goes flush into the headstock On my LTD Viper, there is a little lip. Like right around where I put my thumb when I'm playing some first fret stuff. What's that little lip called? I think that I don't prefer it. I'd rather not have it, but I guess it doesn't bother me very badly either. Here's my question: is it something built purposely as something that guitarists want to have? Like some people want to feel that little lip there when they play? Or is it a biproduct of creating a sturdier neck or something like that?
