This video shows how to use a Q-tip to hold the whammy bar / tremolo arm on a Strat (or other guitar) in place so that it doesn’t dangle. Unlike other methods such as using plumber’s tape, you can set the whammy bar to either stay put or dangle when you’re not using it. This method was apparently invented by Stevie Ray Vaughn’s guitar tech, who used it for years.
