Alternate picking - the secret technique
Obviously its not a secret, the inside outside technique, but what im presenting to you here is a very sxrutinized look at what exactly goes on when you play alternate picking and giving you a example on how to clean up your sound with a specific way of practicing

Why does my alternate picking sound like crap?

Some of the explanation could be what im describing in the video because as I also have noticed that even some great guitarsists has this problem too. 

Its realy interresting that the curve you do when you play outside needs to be larger than the curve you need to do when you do the inside picking simply because the string you just played still is pressed to the fret as opposed to in the the outside picking the string you cross needs to be released in order to avoid string noise and theis results in that you need to lift the fick further away from the string leaving you a bigger curve
