Hey everyone! I found a warwick fortress one 4-string bass in red at a pawn shop today. they're asking $399, but it has some pretty noticeable dings and scratches on the bottom edge of the body, and the back plate is being held on with tape. How do i tell if its worth the price? What should i look for as far as other things being broken on it? Also, how do i accurately figure out when it was made? Any help would be appreciated! Thanks!
