I've had it for 3 months, and I couldn't be happier. It was difficult for me to order it, because I didn't read anything but complaints about how complicated it is to manage its application, and that it is mandatory to buy premium download packs. Nothing further from reality. The factory presets are not bad, there are better and worse ones. If you don't like them, you can download practically any amplifier and cab you want, as well as all kinds of overdrive or fuzz pedals, absolutely free, and in a very simple way (I don't understand people who complain so much about the software), it works fantastically. . Another different thing is that you have to investigate among the thousands of profiles there are and find your favorites, that takes time, but the pedal is great.
I use it with a power amplifier to a 4x12 cabin, and it is great.
There is a test on YT by Tim Pierce of the Tone X, and he says he would pay double for it. He compares it head to head with some of his amps, and nails them. I agree with him..
