i agree with snork. i learn for two years, learning on my own, by ears and books that i bought, learning tabs on the net and stuff. but then, on my third year of learning, a friend came by and open me up with stuff that i've never know... which in particular, shred music. he teach me the scales, mode, fingering exercise.... stuffs.... even if i still can't play like a shredder, i can play an extra faster than what i can, two years back. get a teacher or someone that can guide you better. auido is good. text is good. with visual... you're up to advancement in no time...
