Fender UltraCore 9250 Roundwound Bass Strings (45-100)

Fender 9250 UltraCore Nickel Plated Steel Bass Strings are built for players who demand power, precision and reliability from their gear. This 9250ML set pairs a bright, articulate top end with a commanding low end, giving your 4 string bass a punchy, modern voice that cuts through any mix while still feeling smooth and fast under the fingers.

At the centre of each string is Fender’s reinforced UltraCore high carbon steel core wire, designed for rock solid tuning stability and impressive strength under heavy playing. Wrapped in premium nickel plated steel with a classic roundwound finish, these strings deliver a responsive, dynamic tone that works brilliantly for everything from tight, picked lines to expressive fingerstyle grooves.

The 9250ML gauge set runs from 45 to 100, offering a familiar medium light feel that balances comfortable playability with enough tension for clear, defined lows. Hex core construction keeps the intonation precise and the tension even across the neck, so your bass feels consistent wherever you play.

Finished with colour coded ball ends in the classic Fender style, UltraCore strings make quick string changes simple and intuitive on any 34 inch scale electric bass.

UltraCore high carbon steel core

At the heart of each string is Fender’s reinforced UltraCore high carbon steel core wire, engineered to handle aggressive playing without compromising stability. This gives you a firm, responsive feel, excellent tuning consistency and the confidence to dig in night after night.

Premium nickel-plated steel wrap

The nickel plated steel wrap wire delivers a bright, musical tone with plenty of clarity and warmth. You get a punchy attack that helps your lines sit clearly in the mix, along with a smooth top end that responds well to dynamics and touch.

Fast, refined roundwound feel

With a bright roundwound construction and carefully balanced 45 to 100 gauges, these strings feel quick and controlled under the fingers. Whether you play with a pick or fingers, the surface feel encourages fast runs, articulate ghost notes and confident bends.

Hex Ccre precision & classic ball ends

Hex core construction keeps the wrap wire firmly in place for precise intonation and even tension across all four strings. The ball end design with classic Fender colours makes identifying and fitting each string straightforward, helping you get back to playing faster.
