Bridge works well with the posts corroded---I adjusted the intonation and height of strings. Strings could use replacing but are playable. I'd clean (mineral oil) the fretboard when changing the strings.
The neck is smooth & straight with no dings, buzzes or dead spots. The body has many dings but only one little one down to the wood (see photo). There is a crack down the back (2 photos) but not thru to the wood. The mystery to me is the wiring of the Seymour Duncans. It seems to work best with all the knobs wide open but that leaves volume control at the amp only.
I'd have this checked out. A medium scale bass is too big for me so it's back to short scale.
