Martin Flexible Core Phosphor Bronze Authentic Acoustic Guitar Strings MA550FX Medium 13-56

It isn't just about flexibility; it's about bending the note till it rings true. 

Martin SP Flexible Core strings have a thin but strong core wire and a thicker wrap wire which allows them to be flexible and easy on the fingers while holding standard tension. SP Flexible Core strings feel soft to the touch, making them ideal for beginners. But don't be fooled by comfort! Just ask Tommy Emmanuel who performs with Martin's SP Flexible Core strings night after night. With SP Flexible Core, you get total flexibility and total control.
