On the console view:
- click on the "Pro channel" button at the top of your guitar track
- activate the compressor 'power' button - it turns blue
- select a small compressor ratio "4" for light compression.
You will lose guitar dynamics here so don't try for too much compression. Also, if you use too much then your noise floor (hiss) will start to become noticeable which then might need some EQ to control it.
For a good acoustic guitar recording the less stuff you do to it the better - actually, some light reduction of EQ around 100-200Hz will remove any 'muddiness' (booming) in your recording which is good to try.
One last thing, Pan L/R settings of maybe 10 O'clock to 2 O'clock are reasonable to use. Panning full right and full left would never be heard in real life - un less the listener were living in the sound hole!
