Ernie Ball Skinny Top Beefy Bottom Slinky electric guitar strings combine the lighter playability of the Regular Slinky set with slightly heavier wound strings than the popular Beefy Slinky set. This combination is the ultimate for lead players who love to bend for solo work coupled with an even beefier bottom end for rhythm and chords. Gauge combination: 10, 13, 17, 32, 44, 54.
