Just a solid, bright tone, roundwound, all business, nickel-plated steel electric guitar power string.
These sets were developed specifically for lower tunings.
They feature a much heavier gauge/core wire combination that will allows your guitar to go lower without losing tone.
A top seller for good reason, the boomers are just an all around reliable great sounding string.
We love the GHS packaging too, because you know you're always getting a fresh set.
Try a set, you won't be disappointed!
