About this item

  • PROFESSIONAL GUITAR STRINGS: Made from monel, a nickel-copper alloy, our Retro acoustic strings provide a reduced pick attack that allows the guitar’s tonewoods to be heard—not overshadowed. These solid guitar strings are the real deal, offering a true, consistent tone.
  • LONG-LASTING DESIGN: Discover your guitar’s true voice. These strings are designed with Martin’s naturally corrosion-resistant materials to protect the core and wrap wire and extend string life while ensuring a quality feel in every note. They’re available in extra-light, custom light, light, medium-light (“Laurence Juber’s Choice”), and medium gauges as well as in the bluegrass-inspired “Tony Rice’s Choice” string gauge.
  • PERFORMANCE READY: Best for rigorous practice and performance, our Retro Acoustic Guitar Strings offer enhanced longevity with a warm natural tone, and they sound great plugged in. If you have finger fatigue after playing or wish bending notes was easier, try a lighter string gauge.
  • 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. Medium-gauge strings deliver more volume and are perfect for larger-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.

Monel is awesome, better than bronze. Sounds better and lasts longer!

These simply do everything I want... I've been searching for these strings for years... or I should say, I've been searching for this sound. I didn't know these existed until a few months ago.These just sound "round" to put it simply. The sound is just straight up thicc... chompky... lorge... or whatever the internet has come up with to avoid the word "fat." They're all that and a bag of apples...Trying to explain tone through the internet is pointless... just buy some if you're looking for anything other than the clanky janky standard acoustic sound. Some people love that sound, but I hate nothing more than fresh phosphor-bronze or 80/20 strings and some of them take WEEKS to get decent... breaking strings was a terrible event because it meant breaking in new strings and I always dreaded breaking them. These just sound good out of the box and get better with time. The biggest thing I've found with these other than their unique depth of tone is that I can make them "growl" when stumming hard and sliding. It's like a very fast subtle growl that's almost like a dirty slide guitarish kind of thing. I play with a lot of string/finger lube and slide a TON, I don't lift my fingers much and these fit that style like a dream. This not that shrieking sound from dragging fingers... it's a very low growl that I haven't actually figured out how to reproduce consistently yet but it just happens when I'm feeling good.I've tried all sorts of picks (do this asap if you've never done it) and my "go to" is still tortex yellow standard picks. I also have several other styles of picks in yellow like the Jazz 3XLs (my very close 2nd fav). Seriously... spend $30 on every pick variety pack on Amazon... you don't realize how wild the difference is and your sound may just be hiding in your choice of pick.I'm rambling... but the picks are relevant here because with these strings NONE of the 30ish different picks sound bad. Not one... they might not be what I'm looking for, but all picks still sound good with these strings. More traditional acoustic strings tend to sound like absolute garbage if you don't have the right pick... so with all that said, I think it's safe to assume these strings just sound better overall than anything else I've tried over the last 15 years. This is the first time I'm buying more than 1 pack of the same strings in at least 5-6 years.

I’m thrilled with these bluegrass strings! They’ve brought newfound tone to every guitar I’ve put them on. I’ve put them on two acoustics, a twelve string and two semi hollow electric guitars. A little bridge modification on the acoustic guitars and , WOW! What tones and twang! My guitars have found a new voice and have come alive! I have had three people inquire and have shared the info of my find. Very happy with these strings!🎶🎵🎶🎶

I'd never tried the Martin Retro strings, so I figured I'd give them a shot. These are good strings and probably just what a lot of people are looking for. Any complaints I have about them is primarily related to personal preference. That said, they're a bit 'twangy' for me, and took some adjustment... after getting used to them I do think they sound alright. I think I'll try a slightly lighter gauge next time.Pros:Well-madeEasy to break inReasonably vibrantG string (string 4) is a wound string, which I personally preferAttractive nickel finishCons:The sound is a bit 'twangy' or 'crunchy'Not great for bendingRelatively short resonance

I've used alot of different strings through the years. These seem to be the best fit and tone for my Martin. Others have commented at jams that my tone stands out, not meaning to brag. Some have commented that these get dull quickly. I haven't heard that yet, they seem to last a normal amount of time depending on how often you play. I really like them. I tried the lighter set and, while nice, the medium set works best for me. I play folk, bluegrass, blues and it all works.

Put these Monels on my Martin GPC 11e and they are night and day better than the stiff, small sounding Martin Superior Performance SP Phosphor Bronze strings I put on just 4 days ago...and are now in my garbage can.The Monels produce a mellow warm natural guitar tone with nice upper harmonics and a real backbone when you lay into them. They are also softer and easier on the fingers that the SPs. Both were 12s but the Monels feel like 11s. These are my new favorite Acoustic Guitar strings.

...sie auf das richtige Instrument aufgezogen werden.Auf meiner Martin OM21 klingen sie furchtbar, sie "zerstören" den Klang des Instruments.Auf meiner Martin 015M klingen sie fantastisch, die besten Saiten die ich bisher auf der Gitarre hatte.Mein Fazit: Super Saiten für Mahagoni Gitarren, eine Katastrophe für Fichte/Palisander.5 Sterne von mir, denn sie haben die richtige Anwendung gefunden!

2、4、5弦がミディアムより若干細ことが影響しているのかフラットピッキングがすごく弾きやすいです。

Le G aiguë (0.23) a pété malgré toute ma prudence et précaution.Le pire, c'est que j'ai remplacé cette corde par une d'un jeu Martin authentic tirant 10 (MA-500)Et malgré toute ma précaution redoublée, elle a aussi pété !Finalement, j'ai remplacé la fameuse corde par une de tirant 12 et ça va.Bref, mauvaise expérience malgré le son magnifique des cordes !

古いオールマホのMartinに張って1ヶ月くらい経つけど音の芯も残っててる。ブロンズやファスファーのような煌びやかさはないけどちょっとクセになるようなサウンド。パーラー系のギターにも合うかも。
