Since I'm using flats on my main bass, the worry and the expense dead strings generate is gone, but I'm also concerned about string life for flats.
Maybe Roger can chime in and gives us his view on this. When should I change my flats? the obvious answer would be when they can't get to intonate well, but are there other factors to consider?
I do let my strings go until the intonation is out. I've learned that I love bright strings, but I'm just not that picky anymore. I'll save keeping brand new strings on for when I have the cashflow to go that nutty or if I ever get an endorsement somehow.
