Ernie Ball Cobalt Slinky Electric Guitar Strings

    Introducing Man vs. Lab with Cory Wong! Ernie Ball artist Cory Wong flew out to the Ernie Ball factory in Coachella, CA to test his ear in our latest video: Man vs. Lab with Cory Wong. In this video, Cory battles the Ernie Ball String Lab in a blind test to determine if guitar string alloys really affect your tone and playing.
