ok this is a really big move, but with my American Jazz Bass V, how much would it be to make it an American Jazz Bass VI lol. Think about this, i would add another tuning machine at the head, change the nut to fit 6 strings, buy a custom 6 string pickup that would fit, and change the bridge. The problem is it has its strings through the body, and i would have to do something about that. Ideas and estimates would be appreciated, p.s. im having a luither do the work.
