Flatwound Cobalt Extra Slinky
Ernie Ball Cobalt Flatwound strings combine the classic roundwound Slinky tone and playability with the smooth feel and reduced finger noise of traditional flatwounds. Slinky Flatwounds are wound with a proprietary cobalt alloy wire, resulting in a set of strings that is perfect for any bassist looking for the sound of roundwounds with the benefits of flatwounds.
