The lead part naturally came to me as soon as I started improvising over the backing track. It's a repetitive melody that I feel stacks well with the previous ideas, as well as other melodies! I can see this as being looped over and over, in the outro of a song.
A distorted tone will work best for this type of lead. Specifically, something nice and fat!
Be sure to check out the backing tracks, and have fun improvising.
