To really get your surf going we need to check out some whammy bar tricks! When you are using a whammy bar there are a couple of different things you can do. The most common thing is just doing some sort of rhythm over chords. Sometimes it's nice to just give it a bit of sway, combined with the reverb it will sound really cool!
Perhaps my favorite use of the whammy bar is the prebend release.
What you do is you hold a chord or note and you press down the whammy before hitting the chord, then you strum it and release and you get a real spooky sound going.
