recently bought a roland cube 15x amp

i'm looking at this website here: http://www.webspawner.com/users/jrheavymetal2/index.html

because Im not good with the settings on my amp. I dont have a lot of the stuff mentioned on the site such as "Drive" and "Presence" and "reverb"

The only controls i have for roland cube is: bass, middle, treble, the 4 lead types (metal, metal stack, distortion, and overdrive) and gain.

What should I do for substitute for the missing controls? does drive=gain? etc...

what lead combos and stuff do you guys suggest for a
1 Nirvana sound
2. a guns and roses, sweet child, sound
3. and a punk, ramones sound?

thanks a lott
