Martin Retro® Acoustic Guitar Strings - Light Gauge 12-54 Nickel/Copper Monel Blend

Martin Retro® acoustic guitar strings set themselves apart with a proprietary Monel nickel/copper alloy wrap wire that reduces pick attack, letting your guitar's tonewoods speak with clarity and warmth. Available in Light gauge (12-54), these strings deliver a tone signature found nowhere else on the market — natural, resonant, and balanced whether played acoustically or plugged in.

For players searching for the best light gauge acoustic strings for bluegrass, fingerpicking, or singer-songwriter work, the Retro® series offers an ideal balance of articulation and warmth. The reduced pick attack characteristic of the Monel alloy blend makes these strings especially well-suited to players who want the guitar's natural voice to come forward, rather than the brightness of traditional phosphor bronze or 80/20 bronze wraps. They perform equally well with piezo pickups, making them a versatile choice for acoustic-electric applications.

Martin's Monel wrap wire is naturally corrosion resistant, extending string life without the artificial coatings that can dull tone over time. The result is enhanced longevity with no compromise to the warm, organic sound that acoustic players depend on — a combination that makes the Retro® series a standout in Martin's lineup for both studio and stage use.
