Ok guys, let me explain. I've never ever used an effects pedal of any sort for the past 3 and 1/2 years, which is how long I've been playing. Not even a distortion pedal. I get different amps out of my VGA3. So what does a whammy pedal really do? I know a lot of guitarists use them, but why would you use one if your guitar has a whammy bar? That's what I'm curious about, like Satch, Vai and Malmsteen all have guitars with floating bridges/whammy bars, so why do they use a whammy pedal????
