UltraCore™ Nickel-Plated Steel strings bring fortified tuning stability and ultra-refined feel to players who refuse to compromise on tone or performance. At their foundation sits a reinforced high-carbon steel core that provides rock-solid pitch control and exceptional strength under the demands of aggressive playing. The premium nickel-plated steel wrap wire adds clarity, warmth, and dynamic response across the frequency spectrum, whilst the patented bullet-end design-built specifically for Stratocaster® guitars-enhances sustain and keeps your instrument locked in tune.
Hex core construction maintains precise intonation and balanced tension across all six strings, reducing the need for constant retuning during sessions or performances. Colour-coated ball ends make string changes quick and straightforward, and the reinforced design offers higher break resistance for extended playing life. Available in 4250L (.009-.042) and 4250R (.010-.046) gauge sets, these American-made strings provide the durability and definition that serious players demand.
