Watch the Squawking Bells online guitar lesson by Chris Buono from 50 Rock Guitar Licks You MUST Know

Pinch harmonics are totally cool, hands down. The trick lies within making contact with the string with the side of thumb after picking the note. Once you get the hang of it, you'll be squakin' away. This lick finds us in the house of Billy Gibbons where the infamous squeals he musters from Pearly Gates (Gibbons beloved '59 Les Paul) rein supreme. Other pinch harmonic purveyors to keep an ear out for are Zakk Wylde, Jon Donais (Shadows Fall), and that guy with the stripes all over his guitar.
