What is the genre?
I kind of think that's the question that makes it very interesting. I'm not sure that I *like* what I'm hearing, but I am entertained by it because it is such a different thing. Microtonal guitars have been around for a bit, but few have found a way to make them as musical as they do. I wonder, though, whether its one of those music for musician things -- the more familiarity you have for how things are generally produced, the more your ears prick up at the trick.
As an aside, with or without a wacky fretboard, microtonality is part of the guitar. When you bend a string imperfectly to the target note, which can be intentionally for effect (or a skill-deficit issue), you get a microtone. Our ears are used to hearing that, but not those notes with simply fretting which makes it sound almost detuned autotune.
