I have a pedalboard setup that utilizes two of these pedals.. And I've sat down with this and the Boss PS-6, and I was surprised that this tracks as good, if not better, than the Boss pedal.
Wanted a Boss PS-6 at first but I couldn't justify paying for it if I'm rarely gonna step on it. After watchin many youtube comparisons I found this may even be a better choice. I'm satisfied with it all in all, the tracking is okay and has the same features as the PS-6. The build is obviously not the best quality, but for the price I don't care :)
This pedal is amazing fun. I bought it just over a year ago from Gear 4 Music for around £34.99. The pedal has so many functions to play with, so many ways to alter the functions and it's hard to get bad sounds out of it. There's not too many pitch shifter pedals around, and this is the only one that I've tried, but I love it, and I love the price.
