Fender UltraCore 4250 Bullet Electric Guitar Strings (9-42)

Fender UltraCore Nickel Plated Steel Bullet End 4250L strings are built for players who want more feel, more stability and more clarity from their Strat. Combining a reinforced UltraCore high carbon steel core with a premium nickel plated steel wrap and Fender’s patented bullet ends, this 9 to 42 set delivers a slick, responsive playing experience with rock solid tuning and a bright, punchy tone that cuts through any mix.

At the centre of each string is Fender’s UltraCore wire, engineered for exceptional strength, elasticity and pitch control. This reinforced core works hand in hand with the hex construction and nickel plated steel wrap to give you a balanced tension across the set, precise intonation and a lively, articulate response whether you are playing glassy cleans or high gain leads.

Designed specifically with the Stratocaster in mind, the bullet end anchors securely in the tremolo block for improved contact, sustain and tuning stability. Colour coded ball ends make string changes quick and intuitive, so you can spend less time restringing and more time playing.

UltraCore high carbon steel core

At the heart of these strings is Fender’s reinforced UltraCore high carbon steel wire, created to withstand aggressive playing while maintaining consistent tuning. The added strength and elasticity help the strings return to pitch quickly after bends and tremolo use, giving you the confidence to play hard without constantly reaching for the tuner.

Premium nickel-plated steel wrap

The nickel plated steel wrap wire delivers a bright, clear top end with a warm, musical midrange that suits everything from clean funk to saturated rock. This premium wrap material also offers a smooth feel under the fingers and a responsive dynamic range, so subtle picking and heavy riffing both come through with definition.

Bullet end design for Stratocaster

Fender’s patented bullet end is designed to seat perfectly in a Stratocaster style tremolo block, improving contact between string and bridge. This helps enhance sustain, tuning stability and overall resonance, particularly when using the tremolo arm, making these strings a natural choice for Strat players.

Light 9 to 42 gauge set

The 4250L gauge set runs from 9 to 42, offering an easy bending feel and a fast, slinky response that is ideal for lead work and expressive vibrato. The lighter tension reduces fatigue during long sessions while still providing enough resistance for solid rhythm playing and tight, controlled picking.

• Reinforced UltraCore high carbon steel: UltraCore wire provides exceptional strength, elasticity and pitch stability, helping the strings stay in tune longer and resist breakage under heavy playing and wide bends.
• Nickel-plated steel for clear, dynamic tone: The nickel plated steel wrap delivers a bright, articulate sound with a smooth feel and strong dynamic response, giving you clarity for complex chords and definition for single note lines.
• Patented bullet end for improved stability: Bullet ends are engineered to fit securely in Stratocaster style tremolo blocks, enhancing sustain and tuning stability while reducing string slippage during tremolo use.
• Hex core with colour-coded ends: Hex core construction ensures precise intonation and balanced tension across the set, while colour coded ball ends make identifying and changing strings quicker and more straightforward.
