Randy Potter mentions; The scoring on the string, so they say, helps the winding remain in place - and thereby produce a larger, fuller sound, since it is not flopping around, not separating from the core wire, so much. Regarding the core wire and the wrap acting as a unit, the next time you replace some strings, unwrap the copper past the swedge on a few single wound strings from your old set. It may surprise you to find that even after years of being wound around that core wire, the copper wrap still expands generously away, quickly and easily sliding back and forth over the core. No adhesion whatsoever. Mind you this is not true 100% of the time, because some manufacturers did scuff the cores. But it is very coincidental that on terrible sounding strings, it is almost always true. The swedge and the twist therefore become a very important part of the unschraffed string's construction. If it is not there, you don't have much of a string. David Sanderson Sanderson Accu-Strings Littleton, MA
