Hi Noel

In it's most basic form the rock/metal solos will use predominantly pentatonic scales, which removes some of the possible dissonance anyway. Playing over the power chord (5) removes some more trouble spots (no major or minor harmonies to worry about).

The soloist (on the example) that comes with band in a box is more complex than that of course, then there is always the speed thing that works, as you say, as long as you don't stress the wrong notes.
