I absolutley adore my Zoom G2, it is a pain in the *** to sift through the menus and settings so you need to spend alot of time with it. However I do get some unbelievable tones out of it. I don't really know or care if the amp models sound like the originals but it gives me tones that work for me and that's really all that counts. I use it in front of the HR deluxe and tend to favour the Marshall Crunch model with the gain backed off to 50ish, really creamy lush bluesy sound. I'd actually pay the price of the G2 just for that sound but then when you add all the other models, stereo effects, really usable noise gate, excellent Eq options....... Love it!

If I was a gigging musician I'd definitly go for the G7 or G9 because of the extra flexibilty for storing and recalling patches on the fly and I'd be interesting to hear how the tube warms the sound. I also love my PODxt but tend to use it just to record, I never got around to getting the shortboard floor controller for it so hence I've not invested too much time in working on a live setup with the POD (it's on my to do list).
