No, we’re not talking about the John Waters flick. There’s a 57-minute documentary about the infamous wah pedal available online right now. As the video is described on Vimeo:

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.

Eddie Van Halen, Paul Gilbert, Dweezil Zappa, Dennis Coffey and other guitarists  …

(E)xplain how a musical novelty transcended convention and has become timelessly woven into the fabric of modern pop-culture.

Great stuff.
