String Construction

Construction is another key component of string performance. D’Addario offers a variety of construction methods to help you achieve your perfect tone and feel:

Round Wound – The most popular and universal construction, delivers that traditional textured feel most players are familiar and comfortable with.

Half Round - We start with a finished round wound string then carefully remove the tops of the windings through our unique centerless grinding technique. Half Rounds deliver a smoother feel similar to flat wounds with the flexibility and tension of a round wound string. Great for reduced finger noise and slide guitar.

Flat Wound – Flattened stainless steel “ribbon” wire wound onto a complex series of under windings. D’Addario Chromes are then polished to an ultra-smooth feel and offer a damped, mellow tone preferred for jazz and twang.

Metallurgy 101

String alloys can have a dramatic impact on your tone, feel and string life. Here is a quick look at D’Addario’s diverse selection of bass string alloys:

Steel - D’Addario’s unique ProSteels alloy is our brightest and most corrosion resistant wire. ProSteels are preferred by many rock, metal and jazz players for their super-bright, piano-like tone and highly textured feel which allows for articulated fingering and pick attack.

Nickel-plated Steel - The industry standard for electric bass and D’Addario’s most popular bass strings. Nickel-plated steel offers perfect balance of dynamic magnetism and smooth, comfortable feel. Their distinctive bright tone is extremely versatile for all styles of music.

Copper-plated Steel – A fine layer of copper is plated onto highly magnetic steel creating a unique combination of sparkly electric tone and rich acoustic overtones.

Pure Nickel - The primary electric string alloy used in the 50s and early 60s. Its lower magnetic properties deliver a slightly warmer, “broken in” tone preferred by many vintage enthusiasts.

Nylon –Non-conductive nylon acts as an insulator for the magnetic core and under windings creating a warm and thumpy tone similar to an upright bass. A classic sound found in many legendary 60s recordings.

EXP Technology

Welcome to EXP Coated Technology, the most natural sounding coated strings available!

How do we do it? D’Addario has developed exclusive wire coating machinery which allows us to fully control all critical variables in the coating process. This groundbreaking process draws wire from rod, anneals, cleans, coats, cures and spools in one continuous process ensuring adherence to extremely tight tolerances. Every spool of wire is tested with sophisticated laser refraction technology which measures coating concentricity to 10,000th’s of an inch ensuring unmatched consistency.

This micro-fine coating is applied to wrap wire PRIOR to winding. Strings are wound normally producing an uncoated feel and tone that last at least 4 times longer.

As hundreds of artists and dozens of guitar manufacturers can attest… you won’t believe they are coated!

What Artists Are Saying
The D’Addario Difference

What makes one string company different from another? Sometimes it’s hard to put your finger on it, but when you play a great string, you just know it’s great. On the surface it might not be evident how or why it’s great… it just is. As they say “the devil is in the details” and the details of the art and science of string making are the key to the D’Addario difference.

It all starts with our exclusively engineered and built string winding machines. There is literally nothing like a D’Addario string machine. The combination of the most advanced computer-controlled winding technology, stringent incoming wire inspection and “quality at the source” manufacturing delivers unmatched consistency, string after string. Additionally, our passion for and commitment to environmentally responsible packaging and raw materials fuels our continued innovation in this area. Last but not least, every D’Addario string is made in the U.S.A. in our Farmingdale, NY facility, ensuring the highest quality and performance.

Through passionate hard work, unrelenting innovation and thanks to you, our loyal customer, D’Addario is the world’s largest string maker, but our undying commitment to continuous improvement ensures we’ll always be there… listening, creating and working to improve the lives of musicians, one string at a time.
