Speed Exercise no. 1
Using the chromatic scale as a training tool is one of the best exercises for achieving a clean style. What I like about this scale is that it can be customized. In reality, any exercise, scale, or mode that you practice with can be customized in a plethora of ways.
The best advice I can give to any guitarist who is serious about improving their picking technique is to think of ways to fool your fingers. Find ways to invert a pattern, to be more specific.
We can accomplish three things by inverting and reconstructing patterns.
1. It broadens our horizons and makes new possibilities visible on the fret board.
2. Your fretting hand is being renewed and challenged all the time.
3. Changes in picking motions are presented to your picking hand on a regular basis.
