I just got a 2004 American Precision that needs a setup. I want to make a string decision, then take it in for the setup. The bass has a string-through-body bridge. I have heard those bridges are not appropriate for flats. That seems silly. A Precision that cannot accept flats? I have also heard that TI Flats are flexible enough for this. Comments? I have also been told the strings might not be long enough. Anybody use TI Flats on a string-through P?
