Guitar Hero 2 Xbox 360: Effects Pedal?

Yes, Joystiq is reporting an additional port on the bottom of the guitar which is labeled as the effects pedal on an insert within the box.

Of course this addition is labeled as "Feature currently not available" but the fact that it was committed to the box means at least they thought about it.

Does this guarantee the accessory? No it does not. It does, however, prove they're not done rocking with this product. More features, more content and perhaps more accessories.

Neat.
