I'd never heard of, or noticed, neck dive 'til I started reading this forum. I guess some would say that both of my Fenders dive, but it didn't ever come to mind. Also, a lot of the time I like to play with the neck nearly upright. This requires the neck to be lifted. The other one I don't understand is "dead spots". I can't seem to find them on either of my electrics. maybe I'm just lucky.
