hey all! I just got a used MIM fender jazz off e-bay (got a great deal), and it arrived today. As I feared, the previous owner had roundwounds on it, and they did a number on the fretboard. Luckily they didn't own it too long, but it's definitely a little gouged. So here's what I'm wondering: If I throw some flatwounds on and play it awhile, will it naturally flatten out the lumps between the grooves and level out the neck? or am I going to have to bite the bullet and sand this puppy down a bit? I'll take pictures tonight when I get home so you can see how deep they are. It's not terrible, but you can feel it by rubbing your fingertip over the fretboard.
