I have this bass and it's original hard shell case with a few scraps on the case. There are no apparent problems with the bass other than the appearance of a black cable through the lower F hole. Apparently, the original owner must have modified/repaired the electronics. The finish is excellent, considering the age. The only thing missing is the foam on the string dampener I have seen similar basses with an asking price of $2,500. Should I list it as is, or get and appraisal, either locally, or try to send it to Gibson for their evaluation? What would you do?
