I wouldn't say "better", my impression is/was that I just preferred the sounds. I think it might have been a feeling of more clarity or something. This might not actually be a good thing to someone else! :lol:
And it might not now for me - it's a very long time since I last used the XTLive for guitars, so my memory might be playing tricks. Btw, I just got the POD 2.0 out at the weekend and discovered I like it!!! (Means my nephew's not getting it now! :lol:) So I might be plugging 6-strings back into the XTLive soon as well, to see what I make of it nowadays....
