Premiums are among the finest electric guitar strings available. Made right here in the United States with cutting-edge computer-based manufacturing techniques, they're wrapped with the finest-quality nickel-plated steel for a silky feel and lasting flexibility. Extreme high-tension windings offer the greatest possible string mass for enhanced pickup response while hex-steel cores prevent winding slippage and ensure long string life. Keep a few sets on hand . . . it could be the best thing you've ever done for your guitar's tone. Gauges: 09-11-16-24-32-42.
