Hit a note, grab the bar and push it down.
Then do the same but pull the bar up.
Then do the same but move the bar up and down quickly.
Then do the same, but pull the bar up, then drop it so it 'bounces' on the springs.
Then do all the above, but after hitting harmonics (natural, pinch, whatever).
Then cup the trem arm in the palm of your hand and randomly depress and release the trem whilst pick tapping on the higher frets.
Go listen to Vader, Peter will inspire you!
As long as the trem is set up properly (make sure it's level with the guitar body when perfectly in tune) it should provide hours of fun!
Enjoy your Floyd!
