Martin M1XX 80/20 Bronze Acoustic Guitar Stringsstar rating 5ScottJuly 10, 2011I really like the 12 and 12.5 sets for my Martin Custom 15 as they have a sparkle that few strings have. Great for bluegrass and folkie strumming as it really cuts through. And, the price is just silly.
Martin M1XX 80/20 Bronze Acoustic Guitar Stringsstar rating 5ChipMay 26, 2010Compared to my usual silk and steel strings these have a bright, metallic sound. Good volume, lots of sustain and overtones. Great price! The sound has really grown on me.
