Did this last night with "Gone Away". Realized today when I watched a RS vid on Youtube that I had reversed 2 notes in the verse. I'll fix that tonight... BTW - that is now my favorite song on RocksmithI had trouble with this one too. And I used to play it in a band in a previous life.
Finally I sat and watched/listened without playing. And it hit me. I was playing 1 note wrong. The note wasn't wrong, but it was one of other guitar parts, not the one charted.
Once I figured that out, instant master mode.
