ONE MORE THING!!!!!!!!!!
The Jazz bass I bought was defretted, meaning someone took the frets off of it to make it fretless. BAD MOVE! Jazz basses have squares of pearl inlay and when you make it fretless, the strings will rattle on the pearl inlay, making most of the notes on the 2nd and 3rd strings impossible to play. I ended up replacing the neck. This could get costly and frustrating. If it was made a fretless bass, it will have nothing on the neck, like a cello. If any pearl inlays are on the neck, watch out.
