It's also a case where through-bridge or through-body stringing could make a difference as well. I've "fixed" dead spots with trussrod tweaks and action adjustments, too. They're more common on the "G" because a 34" scale is the proper length for the vibration period of G, which means that nodes are going to be larger, too. In Rics and other neck-through basses, the rules change because the headstock and bridge are both interacting on the same piece of wood, where on a bolt-on, the difference in headstock pitch is a larger factor. On a set-neck, everything depends entirely on the quality of the joint and the length of the tenon.
