My only issue is that the "OCT + DRY" setting sounds nearly identical to "OCT" setting. I assume it's 50/50 dry and octave but it sounds more like 75/25. I have it in the beginning of my chain and when it goes through the rest of the pedals it sounds like 100% octave and no dry signal. Though it is possible that my crappy amp just plain doesn't handle it well, I'm not an expert :P
I still think it's a great pedal nonetheless though! There is very little artifacting, makes it easy to switch between tunings or playing an octave lower akin to Jack White or Kevin Parker for example. It will stay on my board until I eventually get the DT Whammy for more functionality.
