Great ideas all. I love this forum for the unlimited information that I glean. Some things you might want to try. On time based effects, set them to line up mathematically to the rhythm of the song. The capo idea is great - another alternative if you have an inexpensive acoustic or electric hanging around, re-string it Nashville style. Capo's, inversions, Nashville stringing, different tunings all can allow for 'supporting tracks' that limit the mud.
Mic techniques, and different Mics are your friend to help differentiating each guitar track too. Sometimes, 'all those tracks' are different Mics, in different positions, and placed in various areas in the room, capturing one instrument. You might try a 57 off axis near the grill, or a ribbon centered on the cone 12 inches from the grill. If you have an open back cab, try a 57 in front and in back, both the same distance away from the speaker, pointed about the same place on the speaker, and set one of them out of phase.
One thing that helps for me - I try to flesh out the purpose of the song before I start. Not all times, but more often than not. When I'm recording, I ask myself 'does this part support the theme, emotion and lyrics of the song'. If it does, I keep the track. I might not use it, but it's there. I usually delete any track that doesn't fit, before I even get to the mix process. Don't keep mud. 😀 For me, lyrics are the key in the genre I love. I try to set them up in front of the mix process, as a guide to keep or lose tracks. Even if it's the greatest guitar I have ever played, if it steps on the vocals or lyric image, out it goes!
The nice thing is Sonar reduces the time I'm not playing. With all of the productivity tools it has, I can spend more time with my guitar in my hands, and the creativity switch ON.
