This money saving 2-pack of Ernie Ball Slinky Acoustic Guitar Strings features patented coated Titanium RPS Technology that resists rust and grime for bright and powerful tone time after time.Ernie Ball's titanium coated 2158 Slinky Acoustic Guitar strings are stronger and longer-lasting than traditional strings-either coated and uncoated strings. That's thanks in part to an exclusive protective coating on both the wrap wire and the plain strings as well as a patented winding of titanium wire around the lock twist of the ball end. Staying true to Ernie Ball's heritage of superb craftsmanship and sound quality, Slinky guitar strings are made with the finest and freshest raw materials, resulting in a crisp ringing sound with pleasing overtones.Enhancing the inherent string quality and freshness is Ernie Ball's string packaging. Produced and hermetically sealed into their packages at Ernie Ball's desert headquarters in Coachella, CA, Slinky Acoustic Guitar strings are exposed to minimal moisture and humidity from factory to retailer-insuring that all Ernie Ball strings are as fresh upon opening as they were the day they were made.

Gauges 13-17-26-35-45-56.Martin SP Marquis acoustic guitar strings are designed for maximum tone and longevity. Ultrahigh tensile strength cores resist breaking. Acoustic bronze finish provides greater string life. The silk wrapping on the end is not only a traditional symbol of quality, but provides tighter seating of the string at the bridge pin and helps reduce wear on bridges and bridgeplates.

10-14-22-30-38-48Zebra acoustic-electric guitar strings work great for acoustic-electric guitars with piezo pickups under the bridge or magnetic pickups in the soundhole. Zebras from DR Strings also work for full-size archtop guitars, which respond to Zebra strings with richer tones. Any amplified acoustic comes alive when you put on Zebra strings. Revolutionary design you can see-every other coil is nickel-plated steel, every other coil is rare phosphor bronze, and both are wound on round cores.
