Description
Fender UltraCore Nickel Plated Steel Bullet End 4250L strings are built for players who want a slick, modern feel with rock-solid tuning and clear, cutting tone. Using a reinforced UltraCore high-carbon steel core wire, premium nickel plated steel wrap and Fender’s patented bullet ends, this 9-42 three-pack is ideal for Stratocaster players who value stability, definition and long-lasting performance.
Whether you are bending big solos, digging into rhythm parts or tracking in the studio, UltraCore strings are designed to stay in tune, resist breakage and deliver a balanced response across the neck. The light 9-42 gauge keeps things fast and expressive under the fingers, while the hex core and nickel wrap combine for precise intonation, warmth and clarity that sits perfectly in a mix.
This convenient three-pack keeps you stocked up and ready for gigs, rehearsals and sessions, with colour-coded ball ends to make string changes quick and fuss-free. Made in the USA to Fender’s exacting standards, UltraCore strings give your Stratocaster a refined, articulate voice and a feel that invites you to play longer and push harder.
UltraCore high-carbon steel core
At the centre of every string is Fender’s reinforced UltraCore high-carbon steel wire, engineered for strength, elasticity and consistent tuning. This robust core helps the strings hold pitch even under heavy bending and aggressive playing, so you spend less time retuning and more time playing.
Nickel-plated steel for clarity & warmth
The premium nickel plated steel wrap wire delivers a bright, articulate top end with enough warmth to keep your tone musical and full. Chords ring clearly, single notes cut through with definition and the dynamic response makes it easy to control your sound with your picking hand.
Bullet ends for Stratocaster stability
Fender’s patented bullet-end design is made specifically to work with Stratocaster-style tremolo systems, helping to improve contact with the bridge block for enhanced sustain and tuning stability. The snug fit reduces string slippage and helps your guitar return to pitch more reliably after using the trem.
Light 9-42 gauge in a handy 3-pack
The 4250L set uses a popular 9-42 gauge for a smooth, easy-playing feel that is ideal for fast leads, wide bends and expressive vibrato. Supplied as a three-pack, it offers great value and ensures you always have a fresh set ready for your next gig or recording session.
Key Features
- Reinforced UltraCore high-carbon steel: The strengthened core wire is designed to withstand high tension and aggressive playing, helping to reduce breakages and keep your tuning stable, even when you are bending and using the tremolo heavily.
- Premium nickel-plated steel wrap: Nickel plated steel offers a balanced tonal profile with bright attack and smooth warmth, giving you clear chords, defined leads and a responsive feel that works across clean and driven sounds.
- Patented bullet-end design: Purpose-built for Stratocaster-style bridges, bullet ends seat securely in the tremolo block for improved sustain and more reliable tuning, making them a great choice for players who use vibrato arms regularly.
- Convenient 9-42 three-pack: The light 9-42 gauge keeps tension low and playability high, ideal for expressive techniques and longer playing sessions, while the three-pack format means you can restring more often without running out at the wrong moment.
