So I stripped down my guitar to do a lot of work on it. In the process, I decided to purchase a new neck. From what I've read online, the paper thin gaps between the sides aren't a big deal. However, my gap is between the neck and body close to the pickups (see attachment for picture). The gap isn't huge, but it's much, much bigger than paper-thin.
Is this a problem? If so, what can I do about it? I'm looking to you guys with experience for this.
