WAH-CHICKA-WAH-WAH

No guitar pedal is more well-known and widely used (or over-used if you’re Kirk Hammett) than the Cry Baby wah-wah. If you’ve got some time, dig into this new hour-long documentary on the Wah that started it all and its lasting effect on music, which our Brohemoths at Metal Injection posted over the weekend. Interviews with Eddie Van Halen, Jerry Cantrell, Slash, Kirk Hammett and Zakk Wylde should make it interesting for staunch metalheads while interviews with dozens of other guitar luminaries will delight your inner guitar-nerd.

Oh, what’s that? You’re not made of time? Make sure you at least watch the 2-minute intro sequence in which grown men do their best to vocally imitate the sound of the pedal. Because nothing says “metal” like a 65 year-old dude making funny noises with his mouth. Also, Eddie Van Halen officially sounds like he’s 153 years old.

After the jump, the official description of the documentary:

Cry Baby: The Pedal That Rocks The World tells the story of the wah wah effect pedal, from its invention in 1966 to the present day. Musicians, engineers, and historians discuss the impact of the pedal on popular music and demonstrate the various ways it has been used, as well as how its evolution has improved the ability of artists to express themselves musically. The film features interviews with Brad Plunkett, the inventor of the pedal, plus many other musical luminaries such as Ben Fong-Torres, Eddie Van Halen, Slash, Buddy Guy, Art Thompson, Eddie Kramer, Kirk Hammett, Dweezil Zappa, and Jim Dunlop. These professionals explain how a musical novelty transcended convention and has become timelessly woven into the fabric of modern pop-culture.
