Hi all new to the forums here. I have been playing guitar since the 90's got married and took a break. Now I am back to it once again but the thing I am a bit confused about are picking patterns. I have seen Zakk Wylde live and its a bit confusing because it looks like all down picking maybe because of his insane economy picking but I am not totally sure. Another thing I am confused on what dictates the picking pattern to use the ease of implementation or the feel. Just like for an example Adam Dutkiewicz his chuggy rhythm's baffle me because they are really tight and fast, not to mention changes time signatures with in a song up to three times without losing the rhythm. I really need some guidance I feel like I am stumbling around aimlessly.
