Multi-Effects processors can be a good way to save money. Instead of having to purchase all of the individual guitar effects pedals, you can have them all in one. This can be an advantage or a disadvantage depending upon how much and in which way you use effects.
Multi-FX processors provide an easy way to integrate a multitude of effects and change on the fly between them. This allows you to create and quickly switch between several patches with very different tones.
It is easy to hide your playing by covering it up with effects. Obviously, this is not the goal. So if you decide you would like to use a Multi-FX processor, have fun with all of the possibilities and find your tone.
