How do you get this sound?

no one bringing up The Schoenberg Automaton?
Another interesting sound in the same vein. Do a pick scrape backwards, but with the nail of your thumb. and yes, it does make a different sound than your pick.

are his thicker strings in the middle? thats pretty cool. very different but very cool. unless im just a blind idiot.

hes like me (has strings strung different) cause i string mine backwards so it's eBGDAEB. none of this is relevant, i was just saying words.

Well they tune to GBbFBbEbGC. So essentially it's Drop Bb with a low G.
