Since 1975, GHS Guitar Boomers™ have been THE POWER STRING, and continue to set the standard for musicians in nearly every genre of music. Nickel-plated steel wound over a round core brings a bright tone with a powerful attack, that lasts for an extended period of time. Each string is individually sealed in the GHS Nitro-Pack envelope (with our Anti-Corrosion Guarantee), ensuring they're as fresh as the day we wound them at our factory in Battle Creek, MI.

Modern guitarists are tuning lower and lower, adding more strings for a broader tonal spectrum. Designed with the help of many “extended range” guitarists and featuring tapered ends on our larger (post .070) gauges, our 7-String Boomers™ sets bring what you love about our 6 string sets into lower, uncharted territory!
