Martin MA170 Authentic Acoustic SP Strings, 80/20 Bronze Extra Light (.010-.047)

If you’re chasing that bright, snappy, straight-off-the-shelf acoustic tone, look no further than Martin’s MA170 Authentic Acoustic SP Strings. With their 80/20 bronze alloy and featherweight gauge, these strings deliver a crisp, shimmering sound that’s perfect for players who like their acoustics to sparkle with definition and nuance.

At just .010–.047 gauge, these Extra Lights offer a buttery-smooth playing experience that’s easy on the fingers but still responsive enough to bring your dynamics to life. Whether you're a beginner working on building strength or a seasoned pro needing finesse for fingerstyle or fast chord work, these strings feel effortless right out of the pack.

But don’t mistake light for flimsy—Martin’s SP series is built tough. The high-tensile core wire is engineered to resist breakage and stay in tune longer, while the top-quality 80/20 wrap wire gives the strings a naturally punchy voice with just the right amount of low-end presence. They're the kind of strings that make your guitar feel fresh again—lively, reactive, and full of character.

These are a go-to choice for many players who want their acoustic tone to cut through without sounding harsh or brittle. They shine in studio recordings, bring clarity on stage, and make daily practice sessions feel smoother under the fingers.

Here at Musicmaker, we've been helping players find their ideal acoustic strings since the early days of battered hard cases and well-worn fretboards. Martin’s MA170s are a no-nonsense favourite—affordable, consistent, and inspiring to play.
