The Ernie Ball Mega Slinky strings are the perfect balance between a set of 10s and a set of 11s. Not a hybrid set as you might have seen before but with 'half-gauge' strings instead. These provide the perfect balance of tension from an 11 gauge and flex from a 10 gauge. The SLinky lineup continues to grow and though this gauge might be different from what you've played before, you're in great company by playing Slinkys including Slash, Eric Clapton and Steve Vai. Ernie Ball Nickel Wound Electric Guitar Strings are made from nickel plated steel wire wrapped around tin plated hex shaped steel core wire. The plain strings are made of specially tempered tin plated high carbon steel producing a well balanced tone for your guitar. Gauges .0105, .0135, .0175, .028, .038, .048
