Vibrato systems for guitar

"Stay away from the whammy until you’re out of ideas, because it is way too easy to rely on it. Of course, there’s a skill to it.

[...] You want to use the whammy bar as an accent, not something you rely on. Sometimes, yeah, you need a big divebomb and you want to hit a harmonic and bend the fuck out of it, and I’ve done that too many times in my career."
