I am very much confused. I own a POD (thanx to my neighbor who is Line 6's CTO) and I have heard that you can use the POD as a head on top of your cab. I do not currently own a cab, but I was thinking of purchasing one in hopes that I could use the POD as the head instead of spending more money on that too. Is this true? I am still a beginner so spare me your ribbing, lol . If so, how is this achieved?
