VERITAS™ Acoustic Guitar Strings maintain their tone, tuning stability and intonation thanks to our Accurate Core Technology™. Accurate Core Technology™ creates grooves on the core to cradle the wrap wire into place, allowing the strings to ring out to their full, blissful potential.  A phosphor bronze wrap wire delivers a traditionally bright tone and natural feel.  All VERITAS™ sets include both standard plain steel AND Xenon Power-Plain™ strings, which have increased output to balance with the wound strings.
