So, I'm torturing myself with the Judas Priest version of "Better by You, Better than me... basically, I'm running from an open A to the octave, then a fairly straightforward, but quickly played minor pentatonic run back to the open a (A-G-E-D-C-open A- and it feels like it's being played in triplets) and I'm going nuts. I've practiced this run about a zillion times and I'm having two problems. Problem 1- I end up with the open A ringing, which is a bit distracting. I've tried muting it with my third finger, but that slows me down in reaching for the octave. to make matters worse, I have a tendency to pluck the A string more strongly as I'm preparing to jump to the octave. I'm really fighting this, but I can't seem to cure myself of it. Problem 2- no matter how many times I practice this lick, and think I've got it nailed, when I fire up the CD, my fingers just won't do it. I think part of it is a mental block, I'm overthinking my playing, but there's a dexterity issue as well. Any suggestions on how I can mute the A string while going for the octave, and any exercises that will help my speed/dexterity? I used to live on the minor pentatonic, and I though I had gotten it down to where I could run it pretty quick, but right now, I'm making myself nuts. I've tried playing at the fifth fret position, and that helped a little, but creates another set of problem, because the riff starts on the G fretted on the E string, so I have to change positions in a way that's really awkward.
