My current Rig (some Q's about playing a fest date)

So i am going to be playing out at a pretty big festival date this year (summer fest), its one of the biggest music festivals in the world.

I am playing guitar with the band Hedda (im their 2nd live guitarist)

I have never played anything even close to this size before.

Im thinking of doing a a pretty basic 2x12 + ENGL (and my FX)

Is there anything special i need to know for doing festival's? Any equipment i need or am missing? They (Summer Fest) didn't really tell us what to expect.

If any one can make it, come see us (ill have the date pretty soon)
