D’Addario Coated Phosphor Bronze Acoustic 45-100

The D’Addario EXPPBB170 coated phosphor bronze acoustic bass strings are designed to deliver a warm, resonant acoustic tone with extended lifespan and consistent performance. Built for long-scale acoustic bass guitars, this set combines the natural clarity and richness of phosphor bronze with D’Addario’s EXP micro-coating technology to preserve tone and feel far longer than uncoated strings.

Each string features a high-carbon steel hex core for excellent tuning stability and accurate intonation, paired with a precision-wound phosphor bronze wrap wire that produces strong lows, balanced mids, and clear, musical highs. The ultra-thin EXP coating protects the wrap wire from corrosion and wear without compromising the natural response or familiar roundwound feel.

With a light, comfortable tension and a balanced tonal profile, the EXPPBB170 set is well suited to fingerstyle or pick playing, making it a reliable choice for both live performance and studio work.
