Hi Elizabeth. This might seem complicated, but the end result is so worth it. I use it on any track that needs a little more 'oomph'.
First, play around with some of the EQ and compression presets in under the 'Edit' tab in your Track Info pane (on the right of your screen). You have to enable the effects by pressing the little light button next to the graphic, then, by selecting the 'Manual' drop-down menu, you will see the first two selections - for instance in the 'Compressor' effect slot - are for acoustic guitar sweetening. You will find similar options in the 'Visual EQ' slot.
Next, (and you can skip this part if it seems too difficult or unnecessary), highlight one of your original guitar tracks by selecting (best to click on the track icon at the far left), place the playhead (the red line with the little triangle on top that moves when the song plays) at the very beginning of the track, then press command+D to duplicate that track, or go to the 'Track' menu and select 'Duplicate Track' - this merely duplicates the type of track along with all of the settings from that track that you have saved.
You will next have to physically place a duplicate of the original track recording by highlighting and press command+C or go to the 'Edit' menu and select 'Copy'. Now go back and highlight/select the new track and paste the duplicated original track recording there by pressing command+V or 'Edit'>'Paste'.
Now you have two identical tracks, which I suggest you offset by manually nudging the duplicate the smallest increment you can. At this point, it's probably best if you disable the 'Snap to Grid' function by selecting it under the 'Control' menu. Open your 'Track Editor', if it's not already open, on the bottom of your screen by clicking on the 'little blue scissors' button on the lower left. When you click and drag the actual track recording to the right in the timeline, you will see it correspond in the 'Track Editor' pane. If you've nudged the track more than half a notch down there, you've gone too far - a little goes a long way here: too much and you have an undesired echo effect.
Lastly, on the duplicate track of your first guitar track, nudge your pan-pot a very small degree to separate the sounds. What this basically does is create a stereo-chorus effect, and is a very common professional recording practice.
If you made it this far, you can repeat the process on your secondary original guitar recording track. 😀
