Three generations of string makers

For more than 50 years our family has been committed to crafting guitar strings in Southern California that shape the sound of rock and roll. From the introduction of Slinkys in 1962 to PARADIGM, the world’s most advanced guitar strings ever created, experience the story and passion behind our family’s uncompromising commitment to innovation and tone.


Legendary Tone

The Sound of Rock and Roll

Eric Clapton, Jimmy Page, Keith Richards, Paul McCartney, Pete Townshend, Slash and thousands of other guitarists have relied on Ernie Ball to deliver the iconic tone they are known for. PARADIGM continues our legacy of tone by pushing the boundaries of what a guitar string can be - stronger, more durable and longer lasting, without compromising the sound or feel.

Superior Break Resistance

The Strongest Strings Known to Man

Our new state-of-the-art wire drawing process coupled with our patented RPS (reinforced plain string) technology dramatically increases tensile strength by up to 35% and provides up to 70% more fatigue strength than traditional strings.

Brass Reinforced
Plain Strings

Reinforced Plain Strings (RPS) firmly lock the string to the ball end without the need for a traditional lock twist, which can over-stress the wire and become a breaking point. This patented, Ernie Ball-exclusive technology gives PARADIGM plain strings superior strength and better tuning stability, so you can bend farther and strum harder than on any other guitar string available.

High Strength
Steel Wire

Both PARADIGM plain strings and wound string core wires are made up of ultra fine grain high strength steel using our new state-of-the-art wire drawing process. This re-engineered grain structure means the strings can take a lot more punishment.

Lab tested

We brought PARADIGM strings to Sturbridge Metallurgical Services lab to put their strength and corrosion resistance to the test.

Unparalleled Durability

Longer Lasting Strings - Without the Coating

PARADIGM wrap wire uses an exclusive plasma enhanced process to remove defects and greatly improve corrosion resistance. Our patented Everlast nanotechnology is applied once the strings are wound, changing the way they react to moisture and oils. Get strings that last longer and sound fresher - without the tone-killing side effects of a coated string.

Corrosion Resistant

Our exclusive plasma process enhances all PARADIGM wrap wire before it is drawn down to specific gauges. The high heat of the plasma removes contaminants and smooths out defects for a consistent finish. Ensuring that the wire has a more stable microstructure before it is wrapped means the string will last longer.

Longer String Life

Don’t let anything get between your strings and your fingers. Developed at Princeton University, Everlast is a groundbreaking nanotechnology just nanometers thin that coats the entirety of the wound string, allowing it to repel moisture and oils that would lead to tone-killing buildup.

Tone Uncompromised

Longer lasting strings have always come with a catch; coatings dampen the highs, the way the strings respond, and sometimes even the way they feel. Paradigm leapfrogs these issues with 21st century technology. No coatings, no flaking, zero impact on the legendary Ernie Ball tone you love.
