Re: Behold my new weekly lesson series, Weekend Wankshop!
i've really enjoyed the ones Petrucci put into Rock Discipline. The alternate picking exercises, especially. His ones using speed bursts are perfect; play a chromatic patter (1 2 3 4 on every string), and play it as 4 8th notes followed by 4 16th notes. So every other string is double time basically. Then try doing 1 string as 8th notes, then 2 strings as 16th, etc. make sure you aren't altering your picking style or tensing up when you kick it into high gear on those 16th notes!
