PowerGig Rise of the SixString

You will unlock the Axeworks venue as you progress through the campaign. Gaining Maximum Mojomorphosis is more about using your mojo frequently, rather than waiting for strategic times to use it.

So set up a 3 song setlist either from the campaign menu or Quick Gig menu, choose the Axeworks venue, and use your mojo immediately every time you get it. Should be a breeze...
