i've tried the pod xt and the g2.1
for modulation effects and delays and stuff, and a really decent acoustic simulator, i give the g2.1u the thumbs up
for really nice amp models that are great, + a pitch shifter that the next best you can get to a digitech, then go with the pod xt
both are good for recording direct into a line in as both have cabinet simulations
as for tweakability, theyre almost on par, but the pod xt allows you to connect to a computer and make patches or even download patches from the internet
another thing is that the g2.1 is gig ready, put it on the floor and stomp on it, the pod xt you gotta get a separate foot controller, and at that price, might as well get an xt live
juz my opinion :lol:
