Built for a powerful, articulate bass voice and a fast, refined feel, Fender UltraCore 9250 bass strings pair reinforced high-carbon steel hex cores with premium nickel-plated steel wrap wire. The roundwound construction supports clarity, warmth and dynamic response, while the strengthened core promotes stable tuning, precise intonation and balanced tension. Designed for 34" scale electric basses, these U.S.-made ball-end strings feature classic Fender color coding for easy identification and come in Medium Light (.045-.100) and Medium (.045-.105) gauges.
