Vibrato is one of those 'hard to grasp but oh so important' parts of guitar playing. Just think where Yngwie Malmsteen, BB King or Stevie Ray Vaughan would be without their unique vibrato. It's what makes us reckognize a guitarist after 2 notes - vibrato is what makes playing come alive. And from a subtle warble to Leslie sounds, Shaker Vibrato does what it can to liven things up!
