A disgrace to a trusted name. The A string broke while I was tuning it up for the first time. Strings Direct sent me a new set without any fuss. I have eased the nut slots to eliminate tightness of fit with these new strings and managed to get them all fitted with no breakage. Played for a bout an hour and they sound dead and lifeless. I have been playing and gigging for over 50 years and have never experienced any thing like this. Martin should withdraw these strings from the market until they can sort them out. They make great guitars , I own two, but these strings are not fit for purpose especially at this price !!
Great strings, my guitar is really more playable and is voice is louder with excellent strings separation.
This strings are a perfect match with my Martin 00-15M. Well balanced clarity. I practice/play several hours a day and have noticed that my hands don’t get tired. Tuning stability is incredible,steady as a rock. I highly recommend these strings.
