No need to get hostile. I wasn't trying to be rude. I was only trying to help. Look through >THESE< threads for a lot of information about the PODxt, and both in some. I personally would rather have the XT over the GP (I actually do have the xt), because you can do more with it. With the GP you're limited to using it on your computer, whereas with the XT you can use it with your computer exactly as you would the GP, and use it with an amp or a PA. Sift through those threads I posted, and if you have anymore questions feel free to post them here. Or, if you find a particularly interesting thread, feel free to post in it to revive it. I'm sure others will chime in here if they have any experience with either. It can be a little slow around here at times, but be patient.
Again, I wasn't being rude telling you to use the search function. I was only trying to help you out. Most topics have already been discussed in one way or another. That's why I suggested you use the search. It is a very usefull tool.
Hope you find the info you're looking for.
