It is ironic that the guy talks about intonation and tuning, but uses the whammy bar to embellish the clean chords and then insists on bending random harmonics over and over again. What music calls for that, and surely intonation is a moot point if you are adjusting the pitch constantly with the whammy bar?
I've tried listening to the music of Harry Partch, an early and noteworthy proponent of Just Intonation music. It sounded like a bunch of people kicking scrap metal around whilst an old man rambled on, tonelessly, about train hopping.
