A lighter core wire wrapped in Kovar — a nickel-cobalt alloy — boosts flexibility and playability while beaming out crystal-clear clarity and perfectly balanced tone. Lower tension isn't a compromise, it's a deliberate design choice that opens up your technique and lets you steer every nuance into orbit.
