+1 space.  Just be aware that the POD FX Loop is not the same as a real amp FX Loop.

A real amp has the loop positioned between the pre-amp and the power amp/speaker.

The pod places the loop either before the amp (like pedals plugged into the input) or after the modelled pre-amp/power amp/speaker/mic (like effects applied to an amp recorded at a mixing desk).

In practice this does not make a huge difference.
