Metallica’s Kirk Hammett is no longer the undisputed master of the wah-wah pedal. After facing off with guitarist Mrs. Smith for a ‘Cry Baby Battle Royale,’ the granny shredder emerged victorious, receiving the golden wah-wah plaque to commemorate the historic occasion.

"I'm the number-one wah-wah abuser, Mrs. Smith claimed during an interview on the Mark Agnesi Show. “I abuse the wah more than Kirk Hammett and I've challenged him multiple times to a wah-off. Why are you hiding behind your wah-wah pedal, Kirk Hammett?"

Hammett later took to his Instagram account to accept Smith’s challenge, setting the date for March 8, during a gig with Hammett’s covers project The Wedding Band.

Between cuts from Black Sabbath, Judas Priest, the Ramones and more, Hammett and Smith faced off for over six minutes, wah-ing the crowd into a frenzy.

Admitting defeat, Hammett conceded, “I can’t do it, I can’t compete with that. I can’t compete with four wah pedals at once. I forfeit!. I think I’ve just been out-wahed, people. A moment in history has just occurred.” Smith took her victory graciously, admitting she learned everything she knows from Kirk Hammett.
