About D'Addario
The World's Most Trusted String & Accessory Brand
D'Addario has been making strings for musicians since the 1600s — a legacy that began in Salle, Italy and today continues out of Farmingdale, New York, where every string, reed, and accessory is manufactured to exacting standards. As the world's largest manufacturer of strings for musical instruments, D'Addario serves players at every level, from first-year band students to touring professionals.
At Heid Music, we carry the full depth of the D'Addario catalog across our Wisconsin locations and online — including guitar strings, bass strings, orchestral strings, woodwind reeds, tuners, capos, humidification products, and more. Whether you're a student picking up their first set of strings or a seasoned performer searching for a specific gauge or alloy, Heid Music makes it easy to find exactly what you need.
D'Addario's commitment to precision manufacturing and sustainable practices means you're not just getting a reliable product — you're supporting a company that has pioneered environmentally friendly, corrosion-resistant packaging, a string recycling program (Playback), and manufacturing innovations that consistently set the industry standard.
Why D'Addario
Built Different. Played Everywhere.
Made in the USA
Every D'Addario string is drawn and wound at their Farmingdale, New York facility — subject to proprietary quality controls that third-party manufacturers simply can't match.
Consistent. Every Set.
D'Addario pioneered the use of precision hex-core technology to ensure every string in every set delivers consistent intonation, feel, and tone — critical for students and professionals alike.
Eco-Friendly Packaging
D'Addario strings ship in recyclable, corrosion-resistant VCI packaging that keeps strings fresh until the moment you open them — without the plastic waste of traditional string packaging.
Full Instrument Coverage
From electric and acoustic guitar to violin, cello, bass, clarinet, and saxophone, D'Addario makes strings and accessories for virtually every instrument found in a school music program or on a concert stage.
