Once again thanks! @SlipinLizard was right on with taking breaks. I came back to it a few hours later and it didn't seem "as hard" and I was able to at least make it ring out correctly a couple times. Still haven't got down fully yet, but definitely made/making progress.

@maggior, good advice on practicing only fretting at first. As dumb as it sounds, that had not occurred to me.

Now to work on doing it consistently and trying to figure out how the hell you guys change chords so fast and smooth without making all the racket I am making trying to!
