How does the loop function work? I haven't figured that out yet. My guitars are set up for low action. I have a Fender Professional Strat and Tele and good amp, a left handed player by the way. I use Ernie Ball strings 9-42, a misquote on my part about the 2 finger barre chords, 2 finger power chords. I have learned so Much from GuitarTricks in the last 2 months from Lisa's lessons. I have leaned too slow down and break, the lessons into small pieces and isolate my issues and work on them until I get. For example, I worked on "keep that faith" for 2 weeks everyday until I could play along with the lesson without making mistakes, that is huge. I have learned too play without expectations and just have fun!!!! Thanks everyone
