GHS Big Core Bass strings provide maximum playability and durability while featuring nickel iron alloy cover and core to cover ratios that have been optimized for bright tone. The taper design on the 4th string maintains balance and consistent tone from G to E strings. It is this taper design that increases fundamental bass note accuracy, adds sustain and tone life and insures outstanding E string performance past the fifth fret. For those players who play in Drop D, C Standard and below, yet prefer the feel of strings with regular gauges, the larger core wire supplies note definition and focus while still maintaining excellent feel. When tuned to pitch these strings have slightly more tension than conventional strings, a crucial feature for the low B string in a 5- or 6-string set.
