Acoustic Studio and Stage Performance

A remarkably super-pure bronzed steel core provides higher tensile strength and elongation. Simply said, the SP strings provide greater durability without sacrificing tone or playability so you can stay in tune and play longer.

Martin SP Fingerstyle strings are specifically designed with greater string flexibilty for the fingerstyle player. The lighter cores are made from ultra-high tensile strength steel to resist breaking. A smooth acoustic bronze electro-finish provides warmth and sweetness while accentuating brilliance.
