VERITAS™ Electric Guitar Strings maintain their tone, tuning stability and intonation thanks to our Coated Core Technology™, a process of coating the round core wire, which locks the wrap wire in place and extends string life by protecting the core from corrosion. A Quantum Nickel™ wrap wire delivers more power, brighter tone and greater flexibility and responsiveness. All VERITAS™ sets include both standard plain steel AND Xenon Power-Plain™ strings, which have increased output to balance with the wound strings.
