This is my second post about the same topic...Well, could anyone explain to me some simple ways of how to do this technique? Thanks.
Pick as fast as you can.. No but seriously, work with a metronome (slowly increasing the bpm) to get your picking technique more efficient and more accurate and speed will come
^What he said. And make sure you're moving your wrist as little as possible, excess movement will make it slower and sloppier sometimes. Oh, and thicker picks are usually needed as well.
