The article highlights three 1960s rock songs that showcase the wah-wah pedal, an effect invented in 1966 and released commercially in 1967. It argues that the device quickly became central to classic rock guitar, particularly through the work of Jimi Hendrix, Eric Clapton and Jimmy Page.

The songs discussed are Jimi Hendrix’s 1968 “Voodoo Child (Slight Return)”, Cream’s 1968 “White Room” and Led Zeppelin’s 1969 “Dazed and Confused”. The piece praises Hendrix’s expressive use of the effect, Clapton’s intermittent wah-wah passages and climactic solo, and Page’s broader skill with the pedal.
