Damn, this thing is digital. If you're looking for REAL harmony sounds, you won't like this. However, I do like the digital-ness of the pedal. Many people tried to shy me away from it. I tried it and loved it. I haven't purchased it yet, but it's on the GAS list. I really liked this pedal a lot. I found the down tuner to be cool. I was playing "Take the Power Back" by Rage and I would put the pedal toe up just to play the low D (dropped D song but I was playing it on a bass tuned EADG) and i'd push the pedal up to play the regular notes. Pretty fun. The Guitar Center guy described it as the pedal from Outer Space, and that's pretty true. It's fun jumping between 5ths and 6ths. But like I said, this does not sound like a true instrument. Listen to the Whammy part in the song "Disposition" by Tool to see what I mean. It has a bit of digital "warble," but I like it! Shoot some questions, comment, carrots... you know.
