I had an AX8 for a few years. While I really liked it, all I used was the Friedman models and various effects. I ended up selling it to buy the real deal (JJ Jr), but I liked the grid/block/scene system of being able to trigger multiple effects at once, and so on. I was thinking of adding a few more pedals and building a bigger board, or I could just sell them all and get one of these and have everything I could ever possibly need or want from an effects standpoint. I did email Dave today and he said I should be able to use a TRS cable for the channel switching, so I think I'm good there. My needs are relatively basic. Drive, Delay, Wah, Phaser, Chorus and occasional tremelo is pretty much all I use, but being able to trigger multiple effects at the same time and have everything in one box seems tempting. I did have a POD XT Live back in 2005, but I haven't used any Line 6 products since.
