GHS Balanced Nickels 4-String Bass Strings Light Gauge (37.25" winding). GHS is proud to release Balanced Nickel strings for bass, a combination of traditional string materials and modern string design. Wound over a round steel core with a pure nickel final cover, Balanced Nickels have the same number of wraps from string to string. This yields a tone that is deep but focused, with an extremely even response, no matter where you are on the fretboard. The end result is a balance between tension, flexibility, tonality and playability.
