i know that they sweep and shred n all the good stuff.. but what scales do they use... is it harmonic minor?... i cant tell. and what do they harmonize on cuz their harmonies sound way different from anything else ive heard... but i might be crazy.
Their songs are probably diatonic, just like 99% of Western music. Analyze some of their work and see what they do.
Someones knowledge of guitar companies spelling determines what amps you can own. Really smart people can own things like Framus because they sound like they might be spelled with a "y" but they aren't.
