Martin Authentic Acoustic Guitar Strings, Flexible-Core MA130FX 92/8 Phosphor Bronze

This may help someone looking at these strings: I have a Martin Custom D (I believe it's basically a D-15 with a spruce top) that I bought a couple years ago as my lifetime guitar. I haven't even changed the strings on it yet, but they were getting old and grungy so it was time. I think they were Martin PB mediums. They sounded great, but I thought they were a tad high on tension and thickness. I play electric too so I prefer slightly lighter strings. I decided to give these Silk and Phosphor custom 11 Martins a try. Stringing them was a breeze as I could right away tell they were thinner and more flexible than the original strings. I could tell right away my Custom D lost plenty of volume. From the first chord I finger picked, I was a bit disappointed in the loss of volume and presence. I would be embarrassed to play my guitar in a bluegrass jam with these strings. On the other hand, for practicing around the house and fingerpicking, they are pretty dreamy. I would imagine to move up to the next gauge in these silk and phosphors would help bring up the volume a good bit. They also retain the guitar's natural sound profile, so playing is still a pleasure. The bass is drastically reduced but the mids and treble tones are still there. The guitar has lost some of that signature Martin ring and bass , but I know I can always get it back if I swap back to regular PBs. These strings definitely make my Martin sound a bit more like a Taylor strung with Elixirs, if anyone is interested, which I know most will not be. But it's good to know I can experiment and get different sounds out of the same guitar. For the price, these are worth a try and I have no regrets, especially as practice strings! Just thought I'd update this review: as these strings aged , they actually got better. I swapped them off my Custom D and onto a Martin OM-15. They lost any brightness but they still have a great fundamental tone. They sound close to Martin monel strings now. I still love them and they're getting dark with age but still ring true and sound amazing. Great value!

I bought these for my 96 Fender DG acoustic I've had since new. The guitar has been all around the country and used in places Camping,the beach ECT not good for acoustic guitars. Plus it doesn't spend much time in a case and has never seen a humidifier. So, it has issues. I built and installed a bridge doctor but the neck needs reset as well. These strings are a nice stepdown in tension and help the guitar to be playable. The sound is good and I've gotten a year out of the set. They are a good value and option to keep a old workhorse around a few more years.

I love these strings. I was a little skeptical at first but they are very comfortable and sound great! Martin makes the best quality strings. I would buy again!

D'Addario strings are great! I have their XS Phosphor Bronze on my guitars but tried the Silk n Steel on the mahogany guitars and they are fantastic. Adding mellow tones to the sound. I saw these Silk and Phosphor and had to try them. I put them on a new 0 sized spruce and rosewood guitar. Easy on your fingers, do very well on bending and add just a little brightness to the mellow tone. I have already ordered more.

Been using Flexible Core PB strings for years, but these are my first Silk and Phosphor set. I got these for a 50+ year old guitar that has had a past issue with a belly bulge. The bulge has mostly been removed, but now I want to minimize the tension as much as I can so it doesn't come back. I've been tuning it down a half step for this. Since these strings have about 25% less tension than regular Flexible Core PBs, I felt okay using standard tuning. They have a mellow tone which is pretty pleasant. The highs on this guitar are naturally subdued, so I normally use brighter strings to help. Unfortunately, these strings make it worse. Although the low tension might allow me to use standard tuning, on this guitar, a tuned down a set of PBs sounds better.

I am an older guitar player and use these for mostly Travis picking on my Martin 000-28 EC model guitar. They sound great, good price, stay in tune, and are very easy on my fingers both for picking and chording. Highly recommend!

Really like these strings on my acoustics. Nice feel, minimal stretching, good tone and performance. These are my go-to’s. Can’t beat them for the price.

Great product and service!! Highly recommended!!!

Overnight delivery! Strings sound awesome. Easy to fret. Highly recommend.

Le ho prese inizialmente per la chitarra Eko di mia figlia, 13 anni, che già suona ma con corde bronzo regolari fa un po' fatica. Ora le ho prese anche per la mia Cort. Sono esteticamente molto belle e ben fatte. Il suono è pieno e ha profondità ed effettivamente sono molto più flessibili al bending. Creano meno tensione senza però perdere volume o tonalità. Non sono morbide come le silk and steel Le silk and steel hanno una morbidezza estrema e un touch confortevole ma che testituiscono anche un suono molto dolce (mellow) e sono di colore argento invece che ambrato. Non credo ci sia paragone con le silk and steel in tema di morbidezza, ma hanno certamente una buona suonabilità rispetto alle bronzo "normali". Se si viene da corde con maggiore tensione, sarà necessario regolare il truss rod per dare relief al manico. Operazione facile, basta inserire la chiave nell'innesto dentro la buca e fare 1/4 o 1/2 giro antiorario, ed eventualmente ripetere l'operazione il giorno dopo se non basta. Il manico è di legno e ha bisogno di alcune ore per assestarsi all trazione del truss rod. Quindi veritieri i dati dichiarati sulla tensione. Quindi, ottime per allentare la tensione sul manico e suonare più facilmente la chitarra, anche se rappresentano comunque una soluzione intermedia tra le bronzo e le silk and steel.

nice tone, soft, pleasant to play

These strings are AMAZING!! I stopped playing my acoustic guitar and was only playing electric. When I tried to go back to play the acoustic I had last my strength for barre chords and the guitar felt difficult to play, as though it was a fight. I even took it to a luthier. Had it set up and new strings but I hated it and wanted to sell it. I saw a review online about these strings and I thought that I would try it out. I've put them on today and I am really amazed and have been playing my acoustic all afternoon and no fatigue. Fretting feels easy and the sound is very sweet and dynamic. The feel is great and I am so happy!!

Fantasticas, queria unas cuerdas para mi acustica nueva que no me destrozaran los dedos, con un tacto similar a una guitarra española. Probe tensiones mas light pero nada. Estas lo consiguen, son mas duras que una española pero mucho menos que unas de acustica estandar. Ahora si puedo tocar mi guitarra acustica, antes me costaba mucho y no me acostumbré. El sonido a mi me gusta.
