Description:
Martin MA545 Authentic Acoustic SP phosphor bronze strings are a great choice when you want more punch than standard lights but don’t want the full tension of mediums. The light medium 12.5–55 gauges sit right in between, adding volume, projection, and a firmer feel that suits flatpicking, strumming, and rootsy acoustic styles.
Built with a tin-plated steel hex core and 92/8 phosphor bronze wrap, these strings offer a warm, articulate voice with clear top end and solid low-frequency support. They’re ideal for dreadnoughts, OMs, and other larger-bodied steel‑string acoustics that reward a slightly heavier set with bigger, more focused tone.
