One of the first things you'll start to realize is that you listen to guitar music differently. You'll be able to tell how many guitars are actually playing. And in time, you can tell what effect settings are used.
For example, I used to think "Nothing Else Matters" was two acoustic guitars. But really it's just one. Learning to play that was one of my greatest accomplishments in my youth.
Sadly, the passion I once had is lost. I just don't have to time or the desire to make the time needed to continue to learn and play. I only ever made for a good rhythm guitar. Solo's were never my forte.
Best of luck to you in your endeavor.
