Hello everyone I recently bought a kit from pitbull, its the AGM-3Q I believe.. its an SG style with 3 hum buckers. Anyway I've been moving along and everything is coming out allot better than I expected as I am new to this but I just started painting and staining the neck and after everything dried I picked the neck up and flipped it over and I heard a noise so I shook it a bit and realized that the truss rod is floating around in there.. is this normal? if not is it fixable from a beginner stand point? thank you so much for your time and I really hope its nothing too bad.. thanks again.
