hey again dudes.. so one friend of mine just gave me his line 6 pod xt pro (To give it a try) wich i think u can get some decent nice tones from it if u spend like 500 hours tweeking the hell out of that pod... but when i try to use it with my amp, my friend told me to use it in the fx loop.. but i dont know where to plug that shit i mean in the return ? in the send ? Well thanks in advance..
