Hi guys,

Thinking about getting this pedal,

Can I set it up to play down an octave and up an octave whilst playing a single song at different parts like seven nation army,
I want to be able to change up and down and return to standard without having to change anything with my fingers half way through the song

Sorry if this is a stupid question, I've never owned one of these pedals

I think the octave part is the same as the normal whammy, and if it is then no you can't. You can turn the knob with your foot though, and I think there are actually little wheel attachment thingies that make it easier to turn with your foot.
