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! Review: Would buy again - 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! ## Features - PROFESSIONAL GUITAR STRINGS: Discover your guitar’s true voice.

The ones I have now are hard to push down are these soft or hard strings?** A: These are great strings, but they are medium gauge strings. For strings that are easier to push down I would recommend Light or Extra Light strings. **Q: Is the custom gauge set for the silk and phosphorus strings or silk and steel? The selection (custom) and picture are of 2 different products.** A: The Silk and Steel are a nickel plated string- softer to the touch. The silk and phosphorus sound more like a acoustic. The nickel you will loose some volume. More like a electric string **Q: Are these correct for my martin 12 string dm-12 acoustic guitar?** A: i do not have a 12 string,but martin strings is all i use **Q: what is what is the difference in "silk & phosphor" and "phosphor bronze" strings? Which One has warmer and deeper lows?** A: There is No difference except- the silk have been made a little softer to the touch. Like-slightly sanded off, they are warmer and deeper. They do not last quite as long but worth it to my ear. I’ve played for 25 years- To get a warmer sound you need a Nylon pick. I love the Dunlap 1.38mm Jazz pick. Then I take some 2000 grit sand paper ( you have to buy at auto parts store) and Buff both sides and edge of pointing end that hits the string. Trust me. Makes it Creamy warm. Sometimes works better than other times. But I love it! So all you hear is the Note instead of all the bright metallic overtones.

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! ### ⭐⭐⭐⭐⭐ Great for older guitars with problems. *by R***S on January 14, 2026* 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. ## Frequently Bought Together - Martin Authentic Acoustic Guitar Strings, Flexible-Core MA130FX 92/8 Phosphor Bronze, (Packaging May Vary) - Martin Authentic Acoustic Guitar Strings - Marquis Silked - Martin Authentic Acoustic Guitar Strings, Superior Performance Custom 11.5-47, Silk & HT Steel --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/189445917-martin-authentic-acoustic-guitar-strings-flexible-core-ma130fx-92-8](https://www.desertcart.pt/products/189445917-martin-authentic-acoustic-guitar-strings-flexible-core-ma130fx-92-8) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-23*
