Foundations Nickel in .040–.100 (FN40100L) is the lighter of our two four-string sets.
Foundations Nickel is brighter and more flexible than our Power Wound sets. The strings bend further with less effort and sit easier under the fretting hand, and the top end is crisper. You can spot a set in the pack: Foundations ball ends are red.
Fit: Standard long scale, for most 34" scale basses. About 37.25" usable winding length (ball end to taper), except the .100 E, which is about 37". 48"–49" overall. Measurements are approximate. Made in the USA.
