The EJ10 strings are wound to perfection using state-of-the-art string winding technology, designed and built by D'Addario's expert engineering team. This technology ensures a production range of 500, 000 to 700, 000 strings per day, offering unparalleled productivity, accuracy, and consistency. The EJ10 set also features D'Addario's innovative Hex Core Construction. This precision-drawn hexagonal core allows the wrap wire to grip the core tightly, resulting in superior dimensional stability, enhanced durability, and precise intonation. Furthermore, the EJ10 strings are created using D'Addario's in-house wire drawing machines, which produce musical instrument wire to exact specifications.
