EZ930 medium gauge strings offer a heavier tension resulting in a bolder, more resonant acoustic tone with higher resistance for heavy strumming and flat-picking. 85/15 Bronze combines the brilliance of 80/20 bronze with the longer life characteristics of Phosphor Bronze. The 85/15 Bronze wrap wire is precision wound onto a carefully drawn, hexagonally shaped high carbon steel core, resulting in long lasting, bright sounding tone with excellent intonation Features: - •\tMedium gauge for heavier tension and bolder tone •\tMore resonant acoustic tone with higher resistance for heavy strumming and flat-picking •\tEnvironmentally friendly, corrosion resistant packaging for strings that are always fresh •\tMade in the U.S.A. for the highest quality and performance •\tString Gauges: Plain Steel .012, .016, Bronze Wound .025, .034, .044, .054
