Cobalt Alloy Provides Power and Brilliance

Optimized Hex-Core Enhances Feel and Tone

The P02815 strings feature an optimized hex-core designed to work synergistically with the Cobalt wrap wire. The core and wrap are precision-gauged to the perfect ratio, enhancing flexibility, vibration and tonal richness.
