I've heard many various GT-10 samples online and I find that it pales in comparison to the Pod X3 live I have. I have yet to try it out personally though. The only good point bout the GT-10 I've seen so far is its ability to track notes well to produce good sounding pitch shifting effects, which the line6 unit totally sucks at. So if I'd advice on which of the 2 top end floor board multi effects to get, it's the Pod X3 Live, esp during cm's sale
