Ernie Ball Earthwood Phosphor Bronze Light 12-String Acoustic Guitar Strings are designed to deliver a warm, ringing acoustic tone with excellent clarity across the full range of a 12-string guitar. These strings are constructed using a phosphor bronze alloy (92% copper, 7.7% tin, 0.3% phosphorus) wrapped around a tin-plated hex-shaped steel core, producing a balanced response with clear note separation.
Phosphor bronze strings are known for their smooth feel and slightly warmer tonal character compared to standard 80/20 bronze, while maintaining strong projection and definition. The light 9–46 gauge helps reduce overall tension, improving comfort and playability on 12-string acoustic guitars without sacrificing articulation.
Earthwood phosphor bronze strings are a dependable choice for players seeking consistent tone, reliable performance, and traditional acoustic sound from a 12-string instrument.
