I have the Tonedexter 2, and I'm pretty happy with it. I trained it with the Lifeline and a Remic red, a T-Bone and an SM 57. I ran it on a run of festivals last summer (mandolin/octave mandolin, vox, drums and bass) and I felt that it sounded good.
There have been a number of updates rolled out since last spring when I got it too. Apparently they've improved the accuracy of the training algorithm, added a 90 second looper so you can playback after training and dial in EQ, HPF, etc , to your taste, and they've added reverb options too. I've not had chance to experiment with any of that stuff yet though, but I plan to get down to the rehearsal space and spend a few hours trying to get if even better for this summer.
