If you can market this and produce it at scale I guarantee you'll sell millions of these things to the middle of the road guitar center learning to play guy. That demographic is fucking huge and probably represents 80% of the guitar based economy.
I would market it that way. I would market this as an easy fuss free interface for conjuring classic tones to learn and play with your favorite artists. If possible a Rocksmith style learn along feature would be amazing.
Really impressed with the simple interface, the apparent ease with which you dial up reasonably good jcm 800 and acoustic type sounds, and how the Alexa script seems to automatically dial in a tone to match the backing track.
Really well done. If you get it to market hit me up I guarantee I can sell these things.
