GHS Strings released Bass Boomers in 1975, and altered the course of rock and roll! Winding a nickel-plated steel cover over a hex core, Bass Boomers have a distinct low-mid bump that is aggressive and bold. Equally suited for pick or fingerstyle, the special recipe of stainless and nickel-plate on the low E and B strings keep your sound defined and strong. Hear why millions consider Bass Boomers as THE POWER STRING.
