About this item

  • PROFESSIONAL GUITAR STRINGS: Discover your guitar’s true voice. These strings feature a lighter-gauge version of our Superior Performance core wire combined with heavier wrap wire to deliver a full and balanced tone with increased playability. They’re available in extra-light, custom light, light, and medium gauges.
  • HIGH-QUALITY DESIGN: Made from 92/8 phosphor bronze, these acoustic strings feature top-quality bronzed-steel core wire and bronze wrap wire. They provide increased flex with huge bends and less finger fatigue, making them perfect for beginners.
  • FLEXIBLE CORE: Best for rigorous practice and performance, our phosphor bronze strings are ideal for finger-style playing and note bending. If you have finger fatigue after playing or wish bending notes was easier, these lighter-gauge strings are the solution.
  • VERSATILE STRINGS: String gauge is an important part of getting the best sound out of your guitar. We recommend using only our extra-light through medium-gauge strings on our guitars. Light-gauge strings have a lighter, shiny sound that gives an airy volume and are great for smaller-bodied guitars.
  • THE TONE YOU DESERVE: For every handmade element we craft, we never forget why we do it: to help you set your creativity free. You’ll find a wide range of Martin strings that fit your instrument and playing style. Enjoy incredible tone, no matter what you play.

These have super bright sound, are light weight, easy to bend and i have no regrets. It is funny but i have friends that say i should be using 12-53’s or 13-54-56’s, as if light strings are not macho. I find them durable and plenty loud when I need them to be. The price is right and the strings are great

After having tried several other brands I find these strings to be of superior quality for acoustic guitar

I've been getting these from time to time for years, mostly if I have a gig. They really are super nice and easy to play, and sound great. For about 6-8 hrs, depending on how hard you play. after that they go pretty dead. If you can afford that, go for it.

First of all, they are noticeably brighter than the Martin SP's that I normally use, however, they sound really good (to me).Several months ago, I put a set on my 50+ year-old D12-28 to help reduce the tension/stress the extra strings put on the bridge and top. The specs indicate they should have about 7% less tension than 'normal' strings. Every little bit helps. I've been very happy with the way the new strings sound and play. I still get plenty of volume, and the highs, lows, and mids all sound good to me.So, a couple weeks ago, I put a set on a Martin DJr-10, a 7/8-size dread that has a 'woody', somewhat dark sound. I've always liked playing this guitar, but it can be too dark for some uses (when using the SPs or other strings). The Flexible Core strings have sweetened the sound, while still maintaining its cool 'woody' character. I like it so much, I now find myself choosing to play the DJr-10 more than my D-18. I will likely try a set of these strings on the D-18 too, even though it already sounds great.

Tienen una gran sonoridad y se sienten mas livianas al tacto. Por ser para mi guitarra de 12 cuerdas es duro para los dedos pero con estas cuerdas realmente se aminora la dureza hacia los dedos

I use these on my work guitar. I can pretty much play the opening to Johnny B Goode with all the appropriate bends on an acoustic guitar. Normally, were i to try that, I would regret it. My fingers hurt after a day of teaching bends on acoustic. These strings make it way easier.

They really hold tuning well but the overal sound is rather dull and the lower strings don't deliver much.

他のコメントのような短命(音のヘタリ)ではありません。「私の感じた事)音もウォーム感が気に入りました。

These are good quality strings. I use them on both of my Martin acoustic guitars. They sound good and hold pitch well. They also last for a long time. The flexible core gives them a softer feel which suits my style of playing.
