Mary Spender Chooses Martin Strings

Authentic Acoustic Lifespan 2.0 Phosphor Bronze

Protects the core and wrap wire to prevent corrosion without compromising tone or feel

"When it comes to choosing strings for my acoustic guitar, I know that I 
can trust Martin’s quality and tone. They build beautiful instruments 
for the working musician and I know they want them to sound at their 
best, so why would I play anything else?"
