UltraCore™ Nickel-Plated Steel strings bring fortified tuning stability and razor-sharp definition to players who refuse to compromise on tone or performance. Built around a reinforced UltraCore™ high-carbon steel wire core, these strings provide rock-solid pitch control and exceptional strength under the demands of aggressive playing. The hex core construction ensures precise intonation and balanced tension across all strings, while the premium nickel-plated steel wrap wire adds enhanced clarity, warmth, and dynamic response to every note.
Engineered for durability and consistency, these strings offer higher break resistance and require less frequent retuning, keeping you focused on your playing rather than constant adjustments. Available in 1250L (.009, .011, .016, .024, .032, .042) and 1250R (.010, .013, .017, .026, .036, .046) gauges, they feature colour-coated ball ends in classic Fender colours for quick and effortless string changes. Made in the U.S.A., UltraCore™ strings combine ultra-refined feel with the lasting tone and stability demanded by serious guitarists.
