I've worked with Line6 gear for many years, and was really looking forward to the PODx3, but when I tried it the first time, I realized that it's the same software in the X3 as in the five year old XT. That's when i looked after something else, and luckily found the AxeFX. When I tried i t the first time, I had to get a second opinion, just in case I was having a brain seizure so I asked Fredrik Thordendal to try it too. He said "This feels just like the first time I plugged the guitar in the boosted Marshall in the 80's when i was a kid. Damn!" That's what I felt too. IMO, it's not even comparable to any Line6 gear when it comes to playability and sound. No, it's not a "plug and play-immediate gratification" type of gear, but on the other hand, neither are Line6 when the "best tone" tweaks comes to mind. I used several eq's, custom IR's and more eq's to get the sound I wanted from it. I do the same now, but it's all in the AFX.
It's a lot of money, but it's very cheap piece of equipment IMO.
