1 mic recording.

[Zoutvat]

What is the best way to record a guitar, using just 1 microphone and still get a natural, open and spacious sounding result? Up till now I doubled the recorded track and let a number of plugins do their work (with varying results).

Depends on the player, the guitar (you don’t even say what type), the room and the mic.
Experiment ! No one will ever be able to you on a forum.
Record and compare, and redo it until you are happy.

Electric or acoustic?

You might try a little 'world-izing'.

Playback the track on a loudspeaker placed in a relatively live room, then send only that track to the FX before mixing with original.

Acoustic, more specific: archtop 'jazz' guitar.
