I understand POD Farm perfectly, not too hard to grasp, but the settings on the software don't compare to the Spider III 120 i have. is it possible to run a guitar into the Spider, a line out of the amp into the UX1, and then send that signal to A) the output for the speakers, and B) a computer. and if so, where does the line out of the amp go (the guitar jack, or a line input?)

once again, can i do this (to record on the PC with Riffworks, by the way) :

{ Guitar---> Spider III---> UX1---> speakers/PC }
