Ruger1911

Pardon me for an elementary question. Newly purchased Spider IV. Presets work great. When I attempt to set a channel manually to distortion, such as "Metal", Drive maxed out, I get very little if any distortion. I watched video on Line 6 website to set amp to get a "Van Halen" sound. Followed settings as shown and still get not much in the way of distortion. What am I doing wrong?
