Multi FX

One easy way to have a vast array of sounds straight out of the box is a multi FX unit. These units have virtually all the sounds you could ever want. They often have expression pedals too which you can see on the picture below. One disadvantage of multi FX is the inability to customise your setup. However the sounds onboard are editable and you can save your own settings into banks and patches. Multi FX pedals can start at very reasonable prices for beginner units right up to expensive professional models.
