I bought a used POD X3 online and I probably will be getting it by end of this week. So the only way to create tones is to have the X3 connected to the computer with Gearbox is that correct, once you created your tones and save them I'm assuming there stored within the X3 as well within Gearbox, so when I disconnect the X3 from the computer the tones I created and saved are still within the X3. If I wanted to play my guitar with the X3 and with headphones without the X3 plugged into the computer can I do that.
