okay what i want to with the 500x 1. Record my real amp (not only the with the 500x) (1.2) While using some Effect before Amp and in the Loop 2. "re-Amp" so i can play first and send this signal from the line 6(connected via usb with my pc) and after this send this signal to the amp while recording with the 500x? 3. Everything, record first the signal, send it from the pc/line6 to the amp with some Effect before the amp and some in the loop and record it all in the same time If yes i will order it this week lol
