I bought these because my local store was out of Daddario EXP 26 strings that I am using. I was using Elixir Custom Lights before that, but I changed to EXP 26 since the G string of the Elixirs was constantly breaking. Comparing this set of Martin MSP4050s with the coated strings I used previously, I found that the Martin strings were the hardest to play with very high tension (hard to bend) and they were also very painful to slide your finger across. Sound-wise they are really good and warm sounding and they get brighter the harder you pick the strings which feels very responsive. Although I haven't used these for long, the Martins feel more durable than the Elixirs but I am expecting some degradation in sound over time since these are not coated. Due to the extremely low playability which I wouldn't expect from a .011 set I found these to be of little use to me. But if you don't use full note bends or slides a lot then you may benefit from the beautiful sound of the strings.

Sorry to Disagree

By Anonymous

from Undisclosed

Comments about Martin MSP4050 SP Phosphor Bronze Custom Light Acoustic Guitar Strings:

I'm sorry, but I must disagree withnthose who claim these strings are inferior or do not stay in tune. I use them on all my guitars except the oldest one on which I use the ultra light. I have never had a problem in over 10 years with tuning slipping. Once set, on my Takamines, from the Santa Fe down to the G series, they stay tuned. I can leave a guitar for a month, which happens sometimes with the "G", and pick it up to find the strings are still perfectly in tune. ON the other end, I can play for hours in a performance and not have to retune once. The phosphor bronze is bright initially and then slowly mellows to a nice warm sound which is great on the Santa Fe which has a cedar top. All in all you simply cxan not get a better string for the money. My experience with Elixers is that they do not hold up well to strumming and fast rhythms. Every time I've used them I have had to replace at least one string during a gig. At nearly $20 a set, that's outrageous. In the last 10 years I have only broken 2 SPs and it turned out there was a sharp edge on the bridge saddle of that guitar, an Ibanez, that was cutting them! Replaced that bridge saddle and have not broken another string since! I will never use any other strings!

    Comments about Martin MSP4050 SP Phosphor Bronze Custom Light Acoustic Guitar Strings:

    I have been using these for years. They start off very bright, but warm up quickly. I have never had a problem with them staying in tune. In my honest opinion, they are a good string with a very good tone after the initial break-in.

      Comments about Martin MSP4050 SP Phosphor Bronze Custom Light Acoustic Guitar Strings:

      This string for the everyone, I believe is the best bet out there. They sound exellent, last long, and are very easy on the fingers. I have yet to break one during 2 to 5 hours of non- stop playing. I have been buying this string for the past 2 years, and really stand on what I am saying. I have in the past, bought all the expensive brands, but with inflation bought this one, and have never returned to high cost ones. Buy it! You will Like It!

      When I bought my Guild DC5, I changed strings continuously until I found the strings that work and sound the best. They also have a long lifespan.

        Comments about Martin MSP4050 SP Phosphor Bronze Custom Light Acoustic Guitar Strings:

        These strings are perfect. I had an evil buzz on my low E. I just assumed it was the action on the guitar. I put on these strings and my cheapo acoustic sounds great!

            long lasting brightness. perfect gauge if you have a firm grip on the neck like i do. I've been running martin strings for several years and recently tried a set of john pearse but the brightness just wasnt there so I back to the martin custom lights.
