problem = there are mono plugs, and there are stereo plugs. on the individual guitar tracks themselves, you must ensure you are using mono plugs. on the folder track (and use a folder...don't bother with routing) you must use stereo plugs. reaEq / reaComp just figure it out themselves.
if you're using ampsims, you must use an individual sim on each mono track.
so you have
[Folder track] panned center, with reaEq and that's really all you need. but any plugz here must be stereo plugs.
[guitar L] with ampsim, panned left, anything else must be a mono plug
[guitar R] also with ampsim, panned right, ditto
