Nickel wound guitar strings are made by winding nickel-plated steel wire around a tin-plated, high-carbon steel hex core wire. (same as plain strings, but hex-shaped). The “core-to-wrap” ratio is the combined diameters of the core wire and the wrap wire which creates the overall diameter of the string. Nickel wound guitar strings have a very balanced tonal response with sparkling highs, clear mid-range and defined bass.
