I've heard that bolt-on necks are prone to dead spots in that general range, while neck-through are immune. I don't know if that's 100% accurate or not, but my bolt-on necks have all had some amount of tone reduction in the general 5th fret area of the G. I've never had one that was so bad that I couldn't "fix" it with a little EQ. I wouldn't be surprised if some neck/body/string combinations could get pretty bad, though.
I only own 1 neck-through bass, & it doesn't have any dead areas that I can detect. I've owned others in the past & don't remember any issues.
