I’ve had these on for over a month and am recording an album, but they still sound bright and resonant. ### ⭐⭐⭐⭐ This set poorly manufactured. 2 strings snapped. *by on Reviewed in the United Kingdom 23 August 2023* I bought for my Flambeau 12 string guitar which I have restrung many times over the past 40 odd years - so I know what I'm doing. I'm an amateur player, but do love the sound generated from this Lowden designed instrument.2 of these strings broke/snapped when stringing the guitar. I take my time to stretch the strings - I hate the "pinging" of the strings as they stretch!! Anyway, the restringing process takes a LONG time - a good couple of hours! The high G string broke at the bead. I was able to twist the string around the bead and it held in place. One of the high E strings was bent and snapped at one of the kinks, there was enough length to re-bead and attach, but it snapped again at another of the kinks in it. So I now had 11 strings attached.I sent a message to the manufacturer to report the faulty item. Martin have still to reply to me with a solution.So I contacted Amazon. I did get a resolution... but I had to remove the 11 strings to send back to them - plus the broken one! They can't be used by anyone else and actually seems a waste. They couldn't send out the individual strings. So Amazon paid for the return of an unusable, unsellable item - surely this just costs them money?? Anyway, I'm only a customer and do what I'm instructed to do.A replacement set was delivered the next day which is fantastic, and the strings are better in this set. Just bad luck the first time with a faulty set. Martin usually are a great product and reliable. ## Frequently Bought Together - Martin Authentic Acoustic Guitar Strings - Superior Performance - Martin Authentic Acoustic Guitar Strings, Superior Performance Custom Light 11-52, 80/20 Bronze - D'Addario Accessories Pro-Winder Guitar String Winder, Cutter, Bridge Pin Puller - All in One Guitar Tool - Black --- ## 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.com.ar/products/143106248-martin-ma550-authentic-acoustic-sp-phosphor-bronze-medium-13-56](https://www.desertcart.com.ar/products/143106248-martin-ma550-authentic-acoustic-sp-phosphor-bronze-medium-13-56) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-08-23*
