So I just got a BYOGuitar custom shop LP Jr. double cut kit, and I have a couple of questions: 1. The body has a knot on the top upper bout ("elbow" area). See attached. What should I do? Can I return this for an unblemished body? 2. When I dryfit the neck, there was a little wiggle in the pocket. Is this normal? What should I do? Return the whole deal?
