Oh I had a BC Rich Warlock many years ago, atrocious headstock. Being my first instrument and me being ignorant and all, first string change I started by removing the heavy string first. Big mistake!! The string angle is so severe on the headstock that by the time I removed the D string the G string proceed to tear the nut straight off the neck!!! It was replaced with a brass nut (we're talking 1991 here folks) and I always backed all of them off gradually across strings after that!!! Big, ugly bass. The only thing that prevented neck dive was the big ugly body. The hard case was so big that people thought I had a keyboard in there. Hands down the worst instrument I've ever owned.
Actually the angle might not have been that great, to think of it - it might just have been that there was an angle and the nut was very poorly attached
