Visited my local luthier today to fix the neck twist I have at the end of my Fender Pbass' fingerboard. He says this is a common problem with most basses as the truss rod doesn't do much good at this location of the neck. Years ago, he submitted plans to Fender (he used to work for an authorized Fender service center) for a tailboard that was tapered off at the end. Then, if/when the wood decided to warp, at least the edge of the fingerboard would be level with the rest of the neck. Fender, probably due to higher costs, rejected his ideas. I'm willing to bet that most people on this board who own production basses have or will have this problem with their necks. I was just wondering if there are any builders on this forum who have experiemented with tapering off the end of their necks to compensate for this problem. I know it sometimes irritates me that when I play harder, the strings will rattle off the end of the fingerboard.
