Ernie Ball Slinky Cobalt Flatwound Bass Strings bring together the silky - smooth feel of classic flatwound strings and the high - energy power of Cobalt. With a SuperBright Cobalt ribbon wrap, Cobalt underwraps, and a perfect hex - core to wrap ratio, these new flatwound bass strings are the first to truly feel like a flat and sound like a round. They offer a bright, well - balanced sound and a super smooth touch. Features include gauges of .040, .060, .070, and .095, precision winding with cobalt alloy ribbon wire, a flexible build that reduces finger noise.

Using these Ernie Ball Slinky Cobalt Flatwound Bass Strings is easy. Just replace your old strings one by one. Make sure to tune them carefully after installation. When it comes to maintenance, wipe the strings with a clean cloth after each use to remove dirt and sweat. This will keep the strings sounding good for longer. Avoid exposing the strings to extreme temperatures or humidity, as this can affect their performance. If you notice any signs of wear or a change in sound quality, it might be time to replace the strings.
