This isn't a poll with spreadsheet-based choices; I just want to know about neck problems you've had with basses. I played a guy's fancy custom bass over the weekend with a thru-body neck and graphite reinforcement bars, which nonetheless had a fairly egregious dead spot at the 8th fret on the G string, a dip in the neck under the low "B" string, and a rattly 6th fret. On the other hand, my humble parts P-bass has no graphite reinforcement, but has no dead spots, fret issues, or neck twists.
