SOLID nickel/copper alloy wrap
Reduces pick attack so the guitar’s own tone woods are less overshadowed.

Independent shopping perspective
Martin MTR13 Retro Bluegrass acoustic strings use a SOLID nickel/copper alloy intended to soften the initial pick attack, leaving more room for the guitar’s tone woods to come through. The result is described as both mellow and crisp rather than attack-forward. Naturally corrosion-resistant wrap wire supports a long-lasting set for players who want a consistent acoustic-string voice over time.
