This thing was built by someone who doesn't play guitar, who assumes that the only thing you can do is pick a note or strum a cord, without understanding that different types of strings produce different sounds, and that different types of pickups provide different sound. How do you do pinch harmonics? How do you rake? Is the attack (inital sound) different depending on if you strum up vs down? How do you do hammer-on and pull-offs? How do you trill? How do you dead strum? Electronics cannot replace everything analog - some things just can't be done electronically.
