D’Addario EJ42 Phosphor Bronze Resophonic guitar strings are purpose-built to meet the unique demands of resonator guitars. Featuring a heavier medium gauge set, these strings deliver increased tension, volume, and projection—essential for driving a resonator cone with authority and clarity.

Constructed with phosphor bronze wrap wire over a high-carbon steel core, EJ42 strings produce a warm yet punchy tone with strong midrange presence and clear, cutting highs. This makes them ideal for slide playing, bluegrass, blues, and roots styles where articulation and dynamic response are critical.

The heavier 16–56 gauge provides excellent tuning stability and sustain, especially for players who prefer open tunings or aggressive right-hand techniques. Made in the USA, D’Addario EJ42 strings offer consistent quality, durability, and tone trusted by professional players worldwide.

String Gauges: .016, .018, .028w, .035w, .045w, .056w
