I have to admit, I was pretty skeptical, but I wanted to try it for twelve-string songs without having to resort to buying a twelve-string. With the right settings, placed first in the pedal chain after the tuner, and by picking back toward the bridge, it does a remarkable job of emulating a twelve- in a band situation you wouldn't be able to tell the difference, and as a soloist there are a few clues, but overall it is worth it. Pretty remarkable how it seems to know which stringsit should double/chorus as opposed to having the separate octave. Definitely worth it, and now that I've gone Kemper it is the ONLY pedal I need.
