Martin 3 Pack 12-54 Light Authentic Acoustic SP Phosphor Bronze Guitar Strings AC122818 Earthquaker Astral Destiny Octal OctaveMartin phosphor bronze strings are comprised of 92% copper and 8% tin for a warmer, balanced response than you'd get with typical 80 20 bronze strings. 92 8 phosphor bronze is also a more corrosion resistant due to the trace amounts of phosphorus in the alloy. Lighter gauge strings are an excellent option for light handed playing styles, younger novice players, and playing with lots of bends.
