What is the Story on Carbon Strings?


Carbon guitar strings and carbon strings for other instruments are favored by many players for their loud bright sound. They are made of harder and generally more durable materials than those used in the formulations for traditional nylon guitar strings. Using a material such as Kevlar, which is also utilized for uses such as body armor, does make a marked difference in both the sound and playability of a guitar string, ukulele string, or strings for any other instrument.

The generally narrower diameter and stiffer consistency of a carbon guitar string makes it harder to attain vibrato and results in less sustain when compared to nylon guitar strings. As a result, they are not considered to be as “expressive” as nylon guitar strings. However, the more forceful attack they provide gives them the reputation of being louder and considered more “powerful”.

As with any category of guitar strings, carbon guitar strings vary in characteristics – but as a category, provide a brighter tone color than the category of nylon guitars strings. And as with any guitar string, the only way to know what is best for you and your guitar is to experience them on your own instrument.

While most instrument strings manufacturers offer carbon strings, here are a few popular options:

  1. For those of us exploring mandocello with nylon strings (I recently finished building one and being a classical guitarist/cellist, I really dislike the “steel string” sound and feel – do some research, it seems there are others who feel the same way and use a nylon/wound combo.

    In that case, would the carbons be a good compromise? and then, should I choose the high tension? and then, I am looking at roughly gages of:

    22 for A
    34 for D
    48 for G
    64 for C

    or something close to that…?

    then I would likely need two sets? or would you break them up? or sell me individual strings (two each then?)

    I would very much appreciate your expertise and advise.

    thank you SO very much!

  3. Hi !

    I have a much greater sound on my guitar (Paulino Bernabe Especial) using a set carbon trebles (Paulino Bernabe Especial strings) that the luthier recommends for his instruments.

    These strings are named as medium-high tension.

    My question is, could you recommend me a alternative set of pretty much the same characteristics ? Just a note, I already find those “medium-high” trebles a little “hard” especially down the fretboard, so I would like the tension to be around there, but closely to the “medium” than the “hard” range.

    Thank you in advance

      1. Hello George,

        I would try:
        These are my favorite sounding trebles. Sorry we do not currently have these single strings grouped as a treble set.

        Knobloch Actives CX 1st E Medium Tension, single string

        Knobloch Actives CX 2nd B Medium Tension, single string

        Knobloch Actives CX 3rd G Medium Tension, single string

    2. Hi George Ev,
      on my sprucetop Bernabé Especial Savarez Cantiga (a mixed up set with a carbon D9 do a very good job! They sound more vivid than the Ramirez strings and by the way the PB strings too. The Standard – Solutions (DÁddario ec.) didn´t convince me on the Especial 1981. Cantiga Strings are rather cheap an last pretty long. One disadvantage is, the need some days on the guitar to get the sound-comeout.

  4. As a Flamenco guitarist, the combination of carbon trebles and standard basses are winner. They are powerful and bright on a Flamenco guitar.

    After testing numerous brands, Savarez have it right. They make combination sets of carbon trebles and std basses in a package. Plus, they have selected slightly lower tensions so that when you play Flamenco, it allows for fast playing and punchy rasgeados without sounding like a tin can. The full spectrum of sound is maintained.

    Two particular sets are the best for Flamenco:

    Savarez 510AR Alliance /Cantiga NT Classical Guitar Strings


    Savarez Tomatito T50R NT Flamenco Guitar Strings

    Personally, the Tomatito set are the best. They are the same as the 510AR Alliance but the Tomatito set has that unique G string that doesn’t dull out and stays bright.

  5. I used carbons for 26 years.
    Your observations on CF strings and mine generally correspond but I believe you omit an important drawback of CF.
    The hardness of carbon means they chew through frets at a much faster rate than nylon.
    After 20 years and several full fret replacement jobs on my main instrument I finally “wised up” and now specify stainless frets in all my instruments. Nevertheless i still went back to nylon with a CF third, best of both worlds.
