when the signal from your guitar to your ears becomes distorted due to high voltage in amplifiers or by a pedal of some kind. this is pretty damn basic though, im very suprised you dont already know this from normal living.....

There are two settings-clean, and overdrive.

Clean is just that-clean. It is just the regular sound. Think acoustic, but the electric guitar's interpretation of it.

Overdrive is where you'll get distortion. As you turn the Gain knob up with overdrive switched on, you will get more distortion. Distortion is that "crunch" or "growl" you hear with music. Blues music uses minimal distortion, rock music uses mid-range distortion, Punk uses mid-high distortion, and Hard Rock and metal use heavy distortion.

Hope that clears it up for you.
