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.

    Put these on my electric acoustic. I've used them before and got good service from them. I especially like the tones. Bought again, I would prefer .9 or .10 gauge set. Will purchase again.

            Light and bright, but with a warmth and depth for most any type of music. They resonate so well you may need to bone up on your palm-mute skills for some styles. Great price for the quality. I will buy these as long as they make em!

                  I'm a bass and guitar player, currently deciding between using Martin custom lights vs. lights? Both sound great.
