Ernie Ball Earthwood Medium Light Phosphor Bronze Acoustic Guitar Strings, 12-54 Gauge (P02146) Medium Light (12-54) Single Pack
Overview
Ernie Ball Earthwood Medium Light Phosphor Bronze strings (P02146) are a single set of steel acoustic strings built for players who want a warm, balanced acoustic voice with strong clarity and projection. The wrap wire is a phosphor bronze blend (92% copper, 7.7% tin, 0.5% phosphorus) wound on a brass-plated hex-shaped steel core, producing a bright top end with a rounded low end that suits strumming and fingerstyle alike. Gauges are .012, .016, .024w, .032, .044, .054 (medium light 12-54), with a wound 3rd (.024w) for consistent feel and reduced breakage. Ideal for singer-songwriters, session players and gigging acousticists who want a reliable, articulate set without coated-string compression.
