I just notice the other day that there is a small line, exactly in the middle of the body of the bass. It starts from the back of the bridge(just were the wood of the back of the body ends) to were the front body ends, before the truss rod. I dont think its a crack since its perfectly straight, its seems more as if it was the place were the woods of the top were glued. The problem is that I have never seen it or notice it before, and I have always thought the upper part of the body was one piece of wood, not two. Is this normal??? The bass has been babe, which means its in excellent condition.
