Yeah, they could have also made a better routing for the comparison, cuz I think there's some difference between the model and the pedals due to the input impedance of the pedals (I hear a bit of tone-suck).
Did you take a look at their white-paper? Cuz they say their approach is sort of a hybrid between Wavenet and LSTM which should result in a method that has the best of both, but there are not a lot of details about it in the paper
PS: at that price I'm tempted to buy it just to test it and make a video about it
