A double-locking vibrato is necessary for this. It also works best
with extreme distortion settings (I use a Deluxe Big Muff into a
RAT). Dive down until the low E string is almost completely slack.
Then pick the string. If your rig has enough low end you get sime
great rumbles and floppy speaker noises. While doing this you can
also fret the string and bend it up, creating a sudden bump in pitch.
You can also whammy down just a little more so that the string is
pulled against the magnets of the pickups. This causes a crashing
noise which is abruptly damped. Jiggling the vibrato arm will cause
the string to bang into the pickups repeatedly. If your distortion
and bass response is heavy enough, you can grab the floppy string
with your fingers and move it back and forth across the pickup,
making a scraping sort of noise with each pass.|
