Ok guys, I hear a lot about how much "you need to take lessons!" Personally, I think its a load of crap. I'm tired of people asking how to play guitar! Think of all the people that never took formal lessons, THEY were the ones that made a huge impact! Now think of the uber theory nerds, Yngwie, Satriani... there songs all sound the same. Not to say I don't envy there sheer speed, but I don't believe thats what makes a great guitarist. Now quit asking people "what scales should I learn to play ____ ?" dammit why don't you think for yourself for once? Thats the reason every popular band these days sounds the same, because everybody keeps asking how to play "metal" or whatever...
im self tought and i feel its more of an achievement if you work through something really hard and manage to play it without getting any help. this way you learn what works and doesnt work for you instead of trying to do something that works for someone else i.e. the teacher.
taking lessons does help a lot, im not saying its better than learning yourself, but it helps to have someone teach you what to do and how to do it. I know what your saying about people who have never taken lessons, like clapton, he is one of the best ever, but i think it would take me way to long to teach myself.
