Description

Built by the world’s leading acoustic brand, Martin SP strings deliver strength, clarity, and consistency. Manufactured in Martin’s dedicated Mexican facility, every set is precision-made and sealed in long-life flow-wrap packaging for freshness.

At the core is high-tensile, tin-plated steel for added durability and corrosion resistance, with premium bronze alloys (Phosphor or 80/20) providing bold, punchy tone across all frequencies.

Lifespan 2.0 coating protects both core and wrap wire from corrosion without affecting feel or tone — giving your strings longer life and lasting clarity.
