Ernie Ball revolutionised electric guitar strings in the late 1960's by creating lighter gauges that better suited the rock guitarist, ‘Slinky' strings were born. Ernie Ball Nickel Wound strings feature the best of both worlds; a steel core wound with nickel. This combination of steel and nickel creates a well-balanced sound. A great gauge for lead guitarists, nice and bendy on the thin strings. The Ernie Ball Super Slinky's are the worlds best selling guitar strings & are perfect for almost any style of electric guitar. The next best selling strings are the slightly heavier Ernie Ball Regular Slinky's - the heavier strings are slightly harder to bend, but do give slightly better tone & sustain.
