Bigsby, "Did I do that first? No, I didn't do that first. You've got to look at guys like Lonnie Mack. He showed everybody how to use a wang bar." Prior to Jimi Hendrix, many guitarists used the Fender or Bigsby vibrato to approximate the pedal steel or slide guitar tones found in Hawaiian or Country music. This early vibrato was actuated after striking chords or individual notes; lowering or modulating the pitch as the notes decayed. Hendrix greatly extended the use of vibrato. His studio tracks "Third Stone from the Sun", "Axis: Bold as Love", and "Voodoo Child" (among others) introduced his use of the Stratocaster vibrato. Live tracks such as "The Star-Spangled Banner", "I Don't Live Today", and "Machine Gun" featured vibrato to mimic rockets, bombs, screams and other sound effects—all within the context of blues-based psychedelic rock. Rock bands of all types have used the vibrato for all sorts of effects, especially as a vibrato over chords. David Gilmour of Pink Floyd is also known for his controlled use of the vibrato bar. A more powerful and heavier use of the vibrato bar is the effect created by grabbing and shaking the bar violently. This style of playing occurs often in heavy metal leads. The band Slayer makes heavy use of vibrato bars; their 1986 song "Raining Blood" fully illustrates this style. They often combine vibrato effects with natural and artificial harmonics, to make a "screaming" or "squealing" sound. Kerry King and Jeff Hanneman have used these harmonic squeal effects since 1981. Night Ranger guitarist Brad Gillis has based his entire playing style around the use of the "floating tremolo," specifically the first-generation Floyd Rose unit. Some examples are on "Don't Tell Me You Love Me" and "(You Can Still) Rock in America". Pantera guitarist Dimebag Darrell is often said to have been one of the most influential users of the vibrato bar. He used the bar extensively in all of his studio albums. Kevin Shields (My Bloody Valentine) created "glide guitar," primarily characterized by extensive use of note bending, via continuous manipulation of the vibrato arm on his Fender Jazzmaster. An example of this is the album Loveless. Jimmy Page of Led Zeppelin used a Fender Stratocaster with a "trem" on live versions of the song "In the Evening" to create a pitch change with every chord. Tom Morello (Rage Against the Machine, Audioslave) used an
