hey i’ve been playing guitar for almost 6 years now … im pretty fast .. but not shredding fast .. but i would like to be .. i tried taking guitar lessons with a teacher .. but i don’t think it’s being helpful , plus its really expensive , so i thought maybe it’ll be better if i just buy or download an instructional dvd .. what do you think ?? and any suggestion on which dvd to get ? i checked the one with michael angelo batio , i don’t think its pretty elaborate , he just plays really fast licks and expect us to learn from it … thanks for your help
