The EJ18s are built for musicians who demand power and projection from their acoustic guitar strings. These heavy tension strings produce a bolder, more resonant acoustic tone with increased resistance that’s perfect for aggressive strumming techniques and flat-picking styles, whilst also providing the stability needed for down tuning applications.
D’Addario pioneered the use of Phosphor Bronze in string manufacturing back in 1974, and this innovation has since become the benchmark for warm, bright, and well-balanced acoustic guitar tone. The phosphor bronze winding material offers superior corrosion resistance compared to traditional bronze, ensuring your strings maintain their tonal qualities for extended periods.
Each string features precision winding techniques that wrap the corrosion-resistant phosphor bronze around a carefully drawn hexagonal high carbon steel core. This construction method results in strings that not only sound bright and vibrant but also maintain excellent intonation across the fretboard, giving you reliable performance whether you’re recording in the studio or performing live.
