When you get your hands on a copy of Guitar Hero II, tomorrow, you'll find in the instruction manual the answer to the question which many inquisitive gamers have been pondering: What's that port on the bottom of the axe for? While it's been rumored for an effects pedal since the first shots showing it were released, it can now be confirmed. The manual explicitly states three things, first that it's for an effects pedal.

Would you welcome some footwork when rocking out?
