It isn’t just about flexibility; it’s about bending the note till it rings true. Martin's Flexible Core strings feel soft to the touch, making them ideal for beginners. But don’t be fooled by comfort; they are for professional players too. Just ask Tommy Emmanuel, who performs with Flexible Core strings night after night.

Martin starts with their highest tensile-strength core wire, then tin-plate it on all six strings for added corrosion resistance; because what you don’t see matters. When coupled with their highest quality wrap wire, you get consistent, true tone that you can count on, song after song. With Flexible Core strings, you get total flexibility and total control. Available in 80/20 Bronze and 92/8 Phosphor Bronze.

Martin Authentic Acoustic Flexible Core strings reduce finger fatigue, they are ideal for fingerstyle and note bending, and offer comfort without sacrificing tone.
