How long does it take before flats lose their ability to stay in tune, or before they are too dead? Does this even happen? I have had my fender 9050m's on for about 5 months and they just keep getting better and more soulful. They sound so good! Will this level off at somepoint and they will stay the same? Thanks Damn, I can't understand why most players use rounds. I really hate them for anything besides slap. I love low end thumping fat tone.
