GHS Boomers are the longstanding and original "Power Strings". Using GHS' Dynamite Alloy these strings pack a bold, POWERful, bright punch while being flexible, soft, and smooth to play thanks to the round core. The tension is perfectly balanced across the set with the thinnest wound string (below .020w) having a hex core. Boooomers!" The thing Ive always loved about GHS Strings paired with great guitars, amps, and low-output pickups, is you can HEAR the wood of the guitar. The strings are transparent enough to let the unique character of the instrument shine through." -Nick Perri, Guitarist From 1964 to now, the GHS Boomers series has been the flagship set of GHS Strings. Used by musicians in every genre, the Boomers have shown to stand up to any playing style. Now known as "The Power String", GHS Boomers continue to make their mark on music across the world. The roundwound guitar set is made with Nickel-Plated steel wrapped tightly around a round core wire. The combination provides the string with its bright characteristic and long-lasting tone.
