I think a combination of their software and body-side mechanics with the Russian fretboard apparatus could do some really interesting things sonically. But it would still be less fun to play than the MIT guitar in its current form.
What's up with vimeo though? Almost 2020 and it still doesn't work properly. I don't think I've ever played a video without constant stutters, buffering, etc.
Letting it play all the way through in order to buffer the whole thing, so that you can play it again, this time 'preloaded', results in it starting the download over - arrghh!
Mentioning them because both Kevin Parker and Annie Clark tend to be interesting in their guitar engineering, while creating popular, accessible and increasingly synth-driven pop/rock.
