Bringing together features like a hex-shaped tin-plated steel core string with a nickel-plated steel winding, the Ernie Ball 2225 Extra Slinky Electric Guitar Strings bring classic Slinky tone in one of the more svelte designs. With gauges ranging from .08 to .038, these are some of the lightest strings offered in the Slinky series and offer an excellent route for strummers with a taste for more treble.
