David's Tip of the Day: Different Types of Tremolo and Vibrato - Part 16, Double Tremolo

The most powerful vibrato/tremolo type I've heard came from the late-great William Clarke. He played an intense tremolo or vibrato (very fast tremolo or vibrato with large swing in pitch) and at the same time opened and closed his hands slower than the vibrato, creating a very cool and powerful oscillating effect. Take a listen to "Lonesome Bedroom Blues" from the Blowin' Like Hell release at 2:27. This is a particularly good example due to the first two bars being vibrato only (with no hand movement) and then in the following two bars he used the slower hand tremolo as well to create the double tremolo.
