From their beginnings as a small family-owned business in 1964 to one of the industry leaders, The GHS Strings Company is world-renowned for their high-performance guitar strings. The GHS Boomers are their most popular model, used by the biggest names in the music business. Often called "The Power String," Boomers produce a clear, bright tone for powerful performances. These strings are made with a round core wire, round wound with nickel-plated steel. This gives them extra durability and a long-lasting tone. Each package is hermetically sealed to keep them fresh and free of moisture.
