I have a Martin HD28, didn't change the strings in two years, whatever it came with. They still sounded pretty good, but I thought the time had come. Put these on... bingo, beautiful fresh sound. Guitar has grand piano richness, great harmonics, love it all over again and can hardly put the guitar back in the case... Receommended strings and great price from this Amazon dealer.
