D'Addario () is a family-owned and operated American multinational company that specializes in musical instrument accessories, headquartered in Farmingdale, Long Island, New York.
D'Addario is the world’s largest musical instrument accessories manufacturer, marketing its products under several brands, including D'Addario Fretted, D'Addario Accessories, Evans Drumheads, ProMark Drumsticks, D'Addario Woodwinds, D’Addario Orchestral, and Puresound Snare Wire. 
Having roots dating back to the 17th century, D’Addario was founded in 1973 in a Long Island storefront by Jim and Janet D'Addario. With fewer than five employees, sales revenues were under $500,000 in their first year. In 1974, father John D'Addario, Sr. and brother John D'Addario, Jr. joined Jim and Janet to launch the D'Addario string brand.
Today, the company conducts business worldwide, with offices on four continents including locations in Brooklyn, New York; Houston, Texas; Sun Valley, California; Newcastle upon Tyne, England; France, Germany, Australia and China.
D'Addario manufactures 95 percent of its products in the United States, distributes to 120 countries, and serves more than 3,300 retailers and all major e-commerce sites. Alongside its own products, D'Addario also produces OEM wire and strings for other musical instrument companies.
The D'Addario Foundation, the company’s philanthropic arm, was established in 1979. The foundation works to identify, fund, and partner with grassroots, community-based organizations that improve outcomes for historically marginalized and impoverished children through immersive music education.
History.
Early years.
The Abruzzo region in Italy was an agricultural and sheep herding region in the 1600s, and many shepherds there produced strings made from sheep and hog intestines that were used on instruments such as guitars, violins, lutes, and harps. The D'Addario (phonetically pronounced in American English or in Italian) family's connection to string making can be traced back to the 1600s.
The D’Addario family perfected their craft in Salle for two centuries before an earthquake destroyed their entire town in 1905. It was then that the D'Addario family emigrated to Astoria in Queens, New York to continue the family business. In the company's earliest days, Charles D'Addario imported strings his father made from Salle. Later, he opened a shop out of his garage in Astoria where he began to produce and sell his own gut strings locally. He established C. D'Addario &amp; Co. in the early years of The Great Depression. His son, John D'Addario Sr., grew up learning the trade from his father and ultimately became a partner of C. D'Addario &amp; Son in the 1930s. The company then transitioned from producing gut strings to steel and nylon core strings. Nylon strings adapted a nylon microfilament created by chemical company DuPont to be used in toothbrushes and brooms. John Sr. realized this material would be perfect for nylon harp and classical guitar strings.
C. D'Addario &amp; Son.
In the 1940s and 1950s, C. D'Addario &amp; Son continued to perfect its nylon strings. At this time, the company mainly was producing strings for violins; however, as the rock and roll community grew John D'Addario Sr. saw the opportunity to expand the company's product offerings. In the 1960s, John Sr. established Archaic Musical String Manufacturing Co., through which he produced the first electric guitar strings to have nickel-plated steel alloy. He supplied strings to instrument makers as original equipment and to private-label accounts. John Sr. then merged C. D'Addario &amp; Son with Archaic Musical String Manufacturing Co. to form Darco Music Strings.
Darco Music.
Darco Music Strings capitalized on the booming guitar market in the late 1950s and throughout the 1960s with a combination of innovative string technologies and partnerships with major guitar manufacturers. In 1959, Darco invented zinc-plated steel roundwound bass strings for electric bass guitars. In 1964, Darco offered bronze-wound acoustic and nickel-wrapped electric strings. In 1968, Darco Music Strings developed a strong relationship with the Martin Guitar Company and Darco eventually became a division of C. F. Martin &amp; Company.
J. D’Addario &amp; Company.
In 1973, J. D'Addario and Company launched in Lynbrook, New York, where John Jr. and Jim D'Addario were the two partners of the company. Their father, John D'Addario, Sr. passed away in 2000.
Acquisitions.
D'Addario has made several company acquisitions over the past four decades, including Kaplan Musical String Company in 1981, Evans Drumheads in 1995, Rico Reeds in 2004, Puresound Snarewire in 2007, ProMark Drumstick in 2011 and Super-Sensitive Musical String Company in 2020.
Present day.
Effective January 1, 2020, D'Addario announced that John D’Addario III, son of John D'Addario Jr, and nephew of Jim D'Addario, would become the CEO &amp; President of D'Addario, while Jim D'Addario, one of the company's founders and leaders since its inception in 1973, will be stepping down as CEO and assuming a new dual role as Chairman of the Board and Chief Innovation Officer.
COVID-19 face shields.
In March 2020, after New York State required non-essential businesses to shut their doors due to the COVID-19 pandemic, the D'Addario Research &amp; Development team worked alongside Chief Innovation Officer, Jim D'Addario to develop face shields with the mylar film used to produce Evans Drumheads' G2 heads.
In October 2020, D'Addario received a $341,000 grant from the New York State Government to expand face shield manufacturing operations.
Brands.
D’Addario markets products under a number of brand names, each of which is used on products geared toward a different niche.
Products and innovations.
Strings.
The original 1950s string formula used pure nickel, which created a characteristically mellow sound. In the early 1960s, John D'Addario, Sr., introduced a brighter-sounding, second-generation nickel-plated steel string, which became the industry standard for the next five decades. Today, 80 percent of all electric guitar strings are based on his formula.
In 2014, D'Addario unveiled a new electric guitar string, NYXL. Formulated, created and perfected in New York State, the new strings were redesigned to bend farther, sing louder, and stay in tune better. The reformulated nickel-plated steel alloy boosts amplitude in the 1 kHz to 3.5 kHz range, modernizing overall tone without losing that nickel-plated steel feel.
In 2019, D'Addario unveiled the X Series, a technologically advanced series of strings created for electric, acoustic, classical, bass, and folk instruments. The D'Addario Research and Development team worked to combine all of D'Addario's innovations, such as extended lifespan treatments, New York Steel, and Fusion Twists into one string. Players can choose between XT, for enhanced life and a natural feel, or XS, for maximum life and a smoother feel.
The first portfolio in the series, XT, combines high carbon steel cores, and the most popular alloys with extended lifespan treatment on every string in the set, giving players enhanced break resistance, pitch stability, and long-lasting performance—all while preserving the tone and feel of uncoated strings.
In 2021, D'Addario launched XS Acoustic. Designed for six-string guitar, twelve-string guitar and mandolin, XS offers players maximum life, strength and stability—all without sacrificing tone. XS features a thin film coating (1/10 the thickness of a human hair) that completely protects the wound strings from corrosion, without dampening the tone.
In 2022, D’Addario introduced XS Electric strings, which included a reformulated nickel-plated steel wrap wire that provides a bright tone with increased output, bite, and sustain.
Accessories.
In 1998, D'Addario acquired Planet Waves, a small guitar strap company on Long Island, and began manufacturing its own accessories under the Planet Waves brand name.
Some of the first products Jim D'Addario and the team designed included an Ergonomic Peg Winder with a built-in string stretcher, as well as a line of instrument cables.
Inventor Arthur Pantoja sent an email to Jim discussing the development of a combination peg winder and string cutter. Jim liked the idea, the patent was good, and the prototype worked, but the product needed some fine-tuning. With the help of guitar designer Ned Steinberger, they designed a marketable product called the Pro-Winder, with built-in hardened-steel wire cutters. The Pro-Winder is one of D'Addario's most successful products, and hundreds of thousands have been sold.
Drumheads.
In 1956, drummer Marion "Chick" Evans produced the first commercially viable synthetic drumhead, which also proved to be weatherproof. He subsequently founded Evans Drumheads in 1957, running the company for a few years, making the heads by hand and personally selling them to professional drum shops along the West Coast of the United States. To help run production, Chick partnered with Bob Beals, who later became the company’s owner.
In March 1995, at Musikmesse Frankfurt, John D'Addario Jr. was introduced to Beals, who wanted to retire and was looking to sell the company. The D'Addario's saw this as an opportunity to enter a new market segment, and D'Addario acquired Evans Drumheads, moving the company’s factory from Dodge City, Kansas to Farmingdale, New York.
To improve quality, the new team developed and patented a Low Temperature Forming (LTF) system to bend and shape drumhead collars. One of D'Addario's most significant achievements was Jim D'Addario's idea for an overhead robotic gluing gantry to bond the drumhead film into the aluminum hoops.
In 2013, Evans Drumheads introduced Level 360, a new philosophy to each of its head ranges. A feature on all Evans drumheads, Level 360 technology aims to ensure greater contact and balance between the head and drum with a greater tonal range, allowing the playing surface of the head to sit perfectly level around the entire 360 degrees of the drum’s bearing edge. It also allows for ease of tuning and optimum quality of sound.
ProMark Drumsticks.
Herb Brochstein, a seasoned drummer in the music industry, operated a studio and retail shop in Houston, Texas in the 1950s. A passing salesman sold him six pairs of Japanese-made drumsticks that were of much better quality than domestic sticks. Brochstein recruited Tat Kosaka in Japan to help him locate the factory in which they were made, and in 1957, he founded ProMark to begin selling drumsticks in the United States.
Initially, ProMark sticks were based on American-made models, which Brochstein sent to the factory with instructions on how he wanted them made. When Brochstein made his first visit to the factory, he was met with a startling revelation: that the factory was actually a house where two young guys used hand tools to shape each stick. The sticks made with hand tools were actually more consistent than the sticks being made in America in the late 1950s by the major drum companies. Ultimately, the hand-made quality is what led to the success of ProMark sticks.
ProMark was the first company to introduce Japanese Shira-Kashi white oak into the American market and the only company to successfully market oak sticks in the US.
D'Addario acquired ProMark in 2011, and in 2021, the company introduced the ProMark and ProMarkClassic brands.
ProMark includes the rear-weighted, performance-driven Rebound and Finesse lines, in addition to ActiveGrip and FireGrain.
ProMark Classic represents the feel, look, and straight-ahead performance of ProMark’s golden era, paying homage to Brochstein’s legacy. These sticks are front-weighted and power-focused Forward and Attack lines.
Every ProMark stick undergoes a proprietary multi-stage weight and pitch sorting process called ProMatch, which assures consistency both from stick to stick and from pair to pair.
Kiln-dried wooden dowels are sorted, separated, and batched together based on the model. Using precise methods, raw dowels are cut, shaped, lacquered, and treated, yielding fully-formed sticks. Finished sticks are matched by weight, adhering to the strictest possible tolerances. All sticks are matched according to their tuned pitch, averaging a difference of only 9 Hz within any model.
ActiveGrip, which debuted in 2016, is a patented heat-activated grip coating. The black coating on the sticks gets tackier as the drummer's hands heat up and begin to sweat, essentially eliminating the need for conventional solutions.
ProMark's FireGrain sticks, which debuted in 2017, are inspired by the devastating fire at D'Addario's previous sawmill in Prospect, Tennessee. While the blaze was a tragedy for the company in the short term, it led to the opening of a new sawmill in Elkton, Tennessee. It was also the spark that ignited the idea for ProMark's new line of drumsticks.
Some early findings pointed to other industries using flame-tempering techniques to harden baseball bats and hammer and axe handles, as well as arrowheads. One in-depth search turned out an ancient Japanese wood hardening and preservation method that originated in the 1700s: Shou Sugi Ban. This method is still popular in the construction industry. Its benefits include enhanced durability, UV ray protection, improved longevity and the repelling of insects.
ProMark's proprietary and patented flame-tempering technique was developed by D'Addario's in-house engineering team. Each drumstick is individually passed through a flame tunnel and receives an exterior char. In addition to creating a unique aesthetic, the open flames crystalize trace amounts of tree sap resin that remains in each
