Martin Authentic Acoustic 12-String Phosphor Bronze Acoustic Strings

The Martin MA500 Authentic Acoustic 12-String Phosphor Bronze Strings are built to bring out the full potential of a 12-string acoustic guitar. Martin's Superior Performance (SP) core wire is paired with a 92/8 phosphor bronze wrap, delivering a balanced, rich tone with exceptional clarity and projection.

The extra light gauge reduces finger fatigue and makes complex chord voicings and melodic runs easier to execute, while preserving the full, shimmering sound 12-strings are known for. Ideal for recording and live performance across folk, pop and fingerstyle arrangements, this set offers impressive tuning stability and long-lasting durability thanks to its high-tensile tin-plated steel core.
