This is what works very nicely for me:
Make a duplicate track of your original guitar
Advance one track by 10 ticks and retard the other by 10
Use phase reverse on just one of the tracks.
This works great especially for a doubled rhythm guitar. I like to give a full stereo spread, one track left and one right for a nice big stereo field.
If you need this to work in mono mode, it will be a bit more effective if you go to 15 ticks apiece. By separating the tracks in the opposite
direction from each other by the same amount from center, they will sound like they are on time.
It sounds natural because there’s no fx although you may enjoy seasoning to your own taste. The only thing that will be unnatural is the fact that
both guitars are playing exactly the same thing which takes away a little character but for a quick fix of the whole track, it takes about 30 secs to do.
(phase reverse is under “audio/processes” on the menu bar)
