When by chance I stumbled across a video on youtube talking about this product I was perplexed and went head first to buy it. A full-fledged synthesizer that you play with the guitar. What else do you want gentlemen? the amount of sounds, possible configurations and variations is gargantuan. Obviously you have to invest time to discover all the possibilities it has, learn how it works and configure it to your liking, but once you have it in your hand, the possibilities are endless. The only thing I miss for now is that there is no way (or I couldn't find) to adjust the latency of the strings, from the moment the string is played until it sends the signal to the pedal individually. Otherwise, it's simply a great toy to spend hours experimenting and having fun with.
