I got the X3 Live over the weekend and my first impression is that it's a fantastic piece of gear. Although I have a hell of a lot to learn about the unit, I have downloaded a few custom patches and found them very good. High gains are great, cleans too. Although they need some tweaking to my personal taste you can hear the potential. I must say I have only tried running the unit in front of a clean tube amp so far. I plan on plugging it into the effects return this afternoon which I am sure will improve it again. I know there is plenty of info on the x3 and xt live via the Line 6 Website but there are a few users here and thought it might be good to try and compile a bit of info on the x3 or xt in one thread on MLP. So, if you have anything you think might be useful, anything at all, post those ideas/findings here. Whether it be recording, use with a PA, plugged into a tube amp, settings etc.
