,or does it matter ? I have been using D'Addario Chromes on a couple of my Fender Precisions. I wanted to string up another P-Bass with Chromes, but Guitar Center was out of the gauge I use. I saw some Ernie Ball Flatwounds in my gauge and bought them. Now I've heard these strings are very close but I gotta say, I can't hear or feel any diffirence between the Ernie Ball flats and the Chromes. I now think that these are exactly the same set. Has anybody else experienced this ?
