Watch the Eric Clapton online guitar lesson by Jeff McErlain from Kings of Tone
The Wah Wah pedal was created in 1966 and has become a staple in a guitarist's arsenal. The pedal is basically a filter that cuts and boosts frequencies and it creates the wah effect. One of my favorite things to do with a wah is to turn it on and leave it in a set position, I picked this up from Michael Schenker. It is also an easy way to approximate Brian May's guitar tone on the cheap!
