The guitar goes into a Stereo all tube pre amp, then right into the computer.
I run stereo into the computer sound card and Guitar rig is all stereo also.
Guitar Rig 3 is doing all the tones.
The pre amp gives your guitar a nice warm starting tone, but it's very clean.
All the delays distortion and effects come from guitar rig and it can do hundreds of different tones.
I have been using it since Guitar Rig 1.
Here's the link to Guitar Rig 3

I have a bunch of hand made Tube amps, but it is way easier to record without mics and all the things that go with that whole situation.
