History of electric guitar strings: 3 key innovations

When we pick up our electric guitar, we often think about the body, the neck, the pickups, the amplifier in front of us. But the strings? We almost take them for granted, right? We change them when they're dead, maybe try a set from a different brand, but we rarely stop to think about how much work, how many insights, and how many “strokes of luck” are behind those metal wires.

The first time I strung a guitar I had assembled, I grabbed the first set I found in a generic store. “Electric guitar strings,” the package said. And that was it. The sound was… meh. Then I started digging, reading, experimenting, and I discovered a world. A world with deep roots, made of metallurgists, musicians who demanded something more, and people who, like us, sought to get the best out of their instrument.

This is not an academic history lesson. It’s a journey through time, a bit like finding ourselves in an old garage, with a couple of beers and the desire to tell each other how we got here. We will see together three moments key that changed the history of electric guitar strings, and consequently, the sound of the music we love. Get ready, because the next time you change a set, you'll have a story to tell.

The dawn of the electric: the vibrating steel wire (and a bit of roundwound)

With the ’50s and ’60s, the electric guitar was no longer a curiosity for a few jazz musicians. It became the voice of a generation. Rock & Roll exploded, electric blues solidified, surf rock brought new crystalline sounds, and country found its twang its trademark. All these sounds required something specific from the strings.

Pure steel strings, despite being bright, had their limits. They could sound a bit too harsh, and their durability wasn't always excellent due to corrosion. And then there was the feel: some found them too stiff, not very 'soft' to the touch.

Key innovation 2: The rise of Nickel-Plated Steel (NPS) strings

Here nickel comes into play. Pure nickel was already used for some types of strings, especially in jazz, for its warm and round sound, and for its corrosion resistance. But it lacked that brightness, that “bite” that was becoming essential for new musical genres.

The solution? Nickel-Plated Steel, or nickel-plated steel. The intuition was to combine the advantages of both metals: the core and inner winding in steel (for brightness and magnetic properties), with an outer layer of nickel (for softness to the touch, corrosion resistance, and a touch of warmth in the sound).

Companies like Ernie Ball, D’Addario, GHS and Rotosound were pioneers in this phase, developing and perfecting these new types of strings. What changed with NPS? Tonal balance: A perfect mix between the brilliance of steel and the warmth of nickel. The iconic sound of classic rock is born here.
Improved durability: Nickel protects steel from oxidation and corrosion caused by hand sweat.
Better feel: NPS strings are generally smoother to the touch than pure steel strings, making bending and vibrato more comfortable. The Ernie Ball and “Slinky” anecdote
Here's a crazy anecdote. In the 1960s, Ernie Ball ran a music store in California. He saw young guitarists buy standard string sets, then break them apart, and buy thinner single strings to replace the thicker ones. They wanted lower action and easier-to-bend strings, but manufacturers at the time didn't make such light sets.

Ernie Ball listened to his customers. He understood there was a demand for more balanced sets with thinner gauges. So, he started producing his “Slinky” sets, with gauges like .010, .013, .017, .026, .036, .046. Heresy for the times! But it was a resounding success. Jimi Hendrix, Eric Clapton, Jimmy Page, everyone was enthusiastic about them. Ernie Ball not only innovated in material, but also in the concept of string sets, making them more accessible and “playable” for everyone.

The sound that was born with NPS is what defined generations of guitarists. Think of the twang crystalline sound of a Telecaster in the hands of a country guitarist, or the powerful and defined riff of a Gibson Les Paul. Much of that sound, that recognizable “voice,” comes precisely from these strings.

Today, NPS strings are the de facto standard for most electric guitarists. I myself, after trying everything, often return to a good set of medium gauge NPS. I find that they offer the best compromise between sound, feel, and durability for most contexts.

If you want to experiment a bit with your sound, before thinking about changing pickups or modify the guitar radically, try changing the type of strings. A set of pure nickel will give you a warmer, more vintage sound, less bright. A set of NPS will give you the classic sound. You'll hear the difference, I guarantee it.

The modern era: coatings and durability (and a bit of experimentation)

Time passes, and the needs of guitarists evolve. In the ’80s and ’90s, with the spread of long tours, intense studio sessions, and the demand for greater sonic consistency, a new problem emerged: string durability. Sweat, dirt, oxidation… strings “died” quickly, losing brightness and intonation.

Changing strings every few days, especially for those who play a lot, is a hassle and a cost. So, the industry began looking for solutions to prolong string life without compromising the sound too much.

Key innovation 3: Coated Strings

The idea was simple: protect the outer winding of the string from everything that ruins it. The solution was to apply a thin polymer coating to the string.

The real breakthrough came in the late ’90s with Elixir Strings, a brand of W. L. Gore & Associates (yes, the same people behind Gore-Tex!). They introduced coated strings, and at first, I must admit, I was skeptical. “Pure marketing,” I thought. “How can a coating not kill the sound?”.

Then, I tried them. And the surprise was great. What changed with coated strings? Extended durability: They can last 3 to 5 times longer than uncoated strings. For those who play a lot, it's a game changer.
Sound consistency: They maintain their brightness and intonation longer, reducing the need for frequent changes and ensuring a more predictable sound.
Feeling: Opinions are divided here. Some find the feel a bit more “slippery” or less “natural.” Others love it. It's a matter of personal preference.
Reduced finger noise: The coating can help reduce finger squeak, which is an advantage for recordings or for those seeking a clean sound. My skepticism and reality
I was one of those who said: “Oh come on, that's stuff for fake professionals”. The truth is that for a garage guitarist like me, who might play the same guitar once a week, the difference isn't that huge. But if you're a musician who plays live three nights a week, or records in the studio, coated strings change your life. Fewer changes, less expense, more time to play.

Elixir has two main types of coating:
Polyweb: A thicker coating, which offers greater protection and a more “soft” and slippery feel. The sound is a bit more dampened, warmer.
Nanoweb: A thinner coating, which still protects well but with a feel more similar to uncoated strings and a brighter sound.

Today almost all major string manufacturers have their coated versions: D’Addario with EXP and then XS, Ernie Ball with Everlast, GHS with Coated Boomers, Cleartone and many others. Each with its own technology, but the principle is the same. A practical tip: If you've never tried them, give them a shot. Maybe on a guitar you use more often. Don't be afraid to experiment. The “best sound” is the one you like and that makes you play better. I found Elixir's Nanoweb to be an excellent compromise for some of my guitars, because they give me the brightness I'm looking for without having to change them every two weeks.

Besides coatings, the modern era has also seen other minor but interesting innovations:
Stainless Steel: Very bright, corrosion resistant, but harder to the touch.
Half-Rounds: A compromise between roundwound and flatwound, with a slightly flattened winding to reduce finger noise while maintaining some brightness.
Cryogenic treatments: The strings are treated at very low temperatures to modify the molecular structure of the metal and improve their durability and stability.

In short, research never stops.

Strings and your sound: a conscious choice

We've had quite a journey, haven't we? From the simple vibrating steel wire, through nickel that defined an era, to coatings that allow us to play longer. The history of electric guitar strings is a concentrate of ingenuity, passion and, above all, listening to the needs of musicians.

The key point of all this is one: strings are not a simple accessory, something to change and forget. They are an integral part of your sound, as much as the wood of the body, the pickup magnets or the amplifier tubes.

Every innovation we've seen has changed not only the sound, but also the way of playing the guitar. Thinner strings have facilitated bending. Brighter strings have paved the way for more aggressive riffs. More durable strings have freed us from the slavery of frequent changes. So, what do we take away from all this? 1. Experiment, experiment, experiment: There is no absolute “perfect string”. There is the perfect string for you, for your guitar, for your musical style. Don't stop at the first set you like. Try different materials (NPS, pure nickel, stainless steel), different gauges (from .009 to .011, or even thicker), different brands.n2. Listen to your guitar: Every instrument responds differently. A Stratocaster might sound fantastic with a set of NPS .010, while a Les Paul might shine with a .011 in pure nickel.n3. Consider your style: If you play a lot of bending and vibrato, a lighter gauge or a softer material might be for you. If you are a fan of heavy riffing and tuning stability, you might prefer thicker strings.n4. Don't underestimate coated strings: If you play often or if your sweat is particularly corrosive (yes, it happens!), coated strings can save you time, money and frustration. Give them a chance, perhaps starting with a Nanoweb set that has a more traditional feel.n5. Change your strings regularly: Even the best coated strings eventually die. An old string not only sounds bad, but can also compromise intonation and tuning stability. Learn to understand when it's time for a change.

I still remember when, the first time I got my hands on a set of pure nickel strings, I felt the difference in warmth and roundness compared to the NPS I usually used. It wasn't a “better” sound, it was simply different*, and it opened my mind to how many nuances there were. It was like discovering a new color on the palette.

The choice of strings is an important piece of your sound puzzle. Don't leave it to chance. Inform yourselves, try, and trust your ears. This is the beauty of DIY: we decide, we experiment, we find our voice.

To delve a little deeper into string production and materials, you can take a look at the resources of historical manufacturers. For example, D’Addario has an interesting section on its website that explains a lot about their history and production technologies. You can find detailed information about their history and products here: [https://www.daddario.com/](https://www.daddario.com/) (consulted on May 16, 2024). It's a good source to understand what's behind the brand you might use every day.

The future of strings: what awaits us (and what I’ve tried)

The journey of electric guitar strings has been long and full of surprises, but it's far from over. What awaits us in the future? It's hard to say for sure, but the direction seems clear: increasingly durable, resonant, and, why not, also more environmentally sustainable materials.

Innovative metal alloys are sought that offer the best in terms of brightness, sustain, and corrosion resistance. Even thinner and more performing coatings are being studied, which do not alter the feel and resonance in the slightest. There are already companies experimenting with nanometric surface treatments, or with completely new materials.

In my small workshop, I've tried everything. I've installed sets of stainless steel strings that seemed made to last forever, but that made my fingers feel like I was playing on barbed wire. I've experimented with the most absurd gauges, trying to find that perfect balance between tension and playability that is somewhat the Holy Grail of every guitarist.

I've also tried some super-eco-friendly sets of strings, made with recycled materials or low-impact processes. The sound? Interesting, sometimes a bit different, but the message is strong. It's nice to see that even in such a “traditional” sector as strings, there are those who think about the future.

The thing I've learned the most, however, is that every guitar is a universe unto itself. What works great on a Stratocaster with single coils might be a disaster on a semi-hollow with humbuckers. And vice versa. There's no universal recipe. There's only the curiosity to try and the satisfaction of finding the right combination.

So, the next time you find yourself changing strings, don't do it mechanically. Think about it. Think about how far those metal wires have come, how many hands have touched them, and how many ears have listened to their evolution. And then, try something new. Maybe you'll discover your next favorite sound. The journey, after all, is the most beautiful part.
