You have to pick the right kind of distortion. Then you choose how heavy the distortion is(value).For example FUZZ value 30. You just have to try the settings out. You can play with the effect at the same time you are editing it. Today i made a very wierd sounding setting. It has Fuzz value 30 from "distortion" and echo value 30 from "pedal". You should try it. When the pedal is up, it gives an echo for the notes you have picked. Then, when you have just picked a note with the pedal up press the pedal down and up again. It gives a really wierd sounding echo. And when you play notes at the same time you are pressing the pedal up and down, you get a scratch sound. You know... that kind of scratch dj`s come up with.
