Flatwound vs Roundwound Guitar Strings

Flatwound and roundwound strings are two of the most popular types of guitar strings. Each one has its own sonic qualities and it is sometimes hard to pick between the two. Simply put, flatwounds are wound with completely flat material and roundwounds are wound clockwise. The latter is the most popular type of string.

While roundwounds are widely used for a variety of genres such as pop and rock, flatwounds are favored by jazz guitarists due to their smooth characteristic. It is also very popular with bassists. Not only because of the tone: the playability with flatwounds is also improved.

In this article, we’re gonna go through the main differences and similarities between flatwound vs roundwound guitar strings, as well as help you decide which one is the best for you.

What’s the Difference between Flatwound and Roundwound?

Flatwound strings, unlike roundwound strings, are wound with a material that has a completely flat surface. This flat surface is what gives the flatwound strings their name. Flatwound strings are often used for slide guitars because of this characteristic, which helps give a better grip to the string in order to maintain a smoother slide and sound.

The flatwound strings are popular with bass guitar players because they have less string noise and help you achieve a smoother slide.

Roundwound strings, on the other hand, are the most popular type of guitar strings. They have a wrap wire that is wound clockwise over a steel core, that’s the reason for their name. These strings sound good and have great sound projection, with a balanced response across the full spectrum, but tend to cause more finger noises than flatwound strings.

Which One Is Right for You?

It depends on a lot of things, such as your playing style and your preferences over tone

Flatwounds are usually thinner than roundwounds and produce a warmer tone. For this reason they are often used by soloists and jazz players who need more clarity in their playing and those who like smoother slides. 

Roundwounds produce more sustain and a brighter sound which makes them ideal for rock, metal, and country: genres that require a lot of weight and projection from the strings. Additionally, they have less tension on the neck which allows for greater comfort when playing long sets at concerts or practicing.

Both types can be used for pretty much anything, so it is a matter of trying and testing which one fits your playing the best.

Are Flatwound Guitar Strings Right for You?

If you are looking for a warmer tone, a very bright sound, or a smooth feel when playing in the upper register, then flatwounds are right for you.  If you want to produce more sustain and want to play with heavier gauge strings, then roundwounds are the way to go. You can also try experimenting with both types of strings and see which one fits your style better.

What Considerations Should You Make When Switching from Roundwound to Flatwound Strings?

The first thing you should consider is your playing style and your music genre. What genre are you playing? If it is rock or pop, then flatwounds may not be the best choice.

If you’re playing jazz, bossa nova, or any style that requires your playing to be smoother, then flatwound strings are a great choice.

As roundwound strings usually have more tension than flatwound ones, you must take your guitar to a luthier for it to be properly adjusted to the strings you’re using on your instrument. This is especially true if the set of strings you’re buying has a different gauge than the ones that were on your guitar originally.

Should I Use Flatwound Bass Strings in my Bass?

It depends. If you’re after a smoother and warm sound with easier playability, then you should consider flatwound string sets for your bass. These are popular among bass players for a reason: they tend to sound very nice in any bass model and provide a full and rounded bottom-end. They don’t have the same mid and highs definition of roundwounds, though.

For that matter, if you’re playing a very aggressive style such as rock and metal where you need lots of mid-range to cut through the mix and you’re frequently using distortion, then maybe roundwound is the way to go. The choice is highly personal, however. Trying it in real life is the only way to be sure.

Frequently Asked Questions

What Is the Advantage of Flatwound Guitar Strings?

The main advantage of flatwounds is that they produce a brighter tone and are much more stable in the upper register. Other than that, flatwound strings give you much smoother slides and bends and reduce greatly the occurrence of string noises and squeaks: that’s why many bass guitar strings are usually flatwound.

Why Are Flatwound Strings More Expensive?

Flatwound strings are a bit more expensive than roundwound ones since they’re not as popular and fewer people use them.

Do Flatwound Strings Have Easier Playability?

Flatwound strings usually have lower tension and will be easier to play on your guitar. This will largely depend on the gauge of the strings, however. Generally, lighter strings are easier to play than those with a heavier guitar string gauge, since they have less tension and are more forgiving to your fingertips.

Are Flatwound Strings Good for Metal?

Yes, flatwounds are generally more stable and have a brighter tone. They’re also less prone to noise, so they may suit metal players better than roundwounds, but that is highly personal.


As you can see, the difference between roundwound and flatwound strings is simple. Roundwound strings have a round wound around them that goes clockwise and are the most popular type. Flatwound strings, on the other hand, are wound with a completely flat material which improves playability and tone.

Whichever is your choice, there is no fast rule. Roundwound strings are usually used in rock and pop music while flatwounds are the best for jazz and bossa nova. Some bassists prefer the flatwound strings too because of the smoother slide they can get with this type of string. It is, therefore, an extremely subjective pick.

If you’re swapping roundwounds for flatwounds, remember to take your guitar to a luthier to have it properly adjusted, so you mantain a stable sound and avoid damaging your instrument.We hope you liked this article.
