Veritas - coated core technology electric Guitar strings: light 9-42. Maintain their tone, tuning stability and intonation thanks to 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.

All veritas sets include both standard plain steel and xenon power-plain strings, which have increased output to balance with the wound strings
