The more I dig into this bass, the more I think I have been robbed!!! I've stripped my 1995 Rick 4001v63 of strings and hardware for some repairs, resto and a refin... It's been sitting like this for at least 6 months... As of today, the neck appears to actually bow backwards! It seems to be the worst in the five frets closest to the nut... Is that normal? Or am I looking at yet another problem???
