I am putting togeter the shopping list for my first build and had a question for some of you who have been through all of this before. When looking attaching the neck to the body using the predrilled holes how do you assure the neck remains straight in line with the bridge. I would assume that you would need to shim the neck pocket as necesary in order to preserve the alignment of body/neck. Is this the case or is the neck pocket accurate enough that considerations are not required to keep the neck in line?
