Guitar Recording Loop?

[uprisemovement]

About 3 years ago I was recording at studio with my band and the producer has sort of amp cycle going on.

Basically from what I remember:
- The guitar was going into the interface and recording on a track in clean with no effects.
- I assume that this track was then being outputted from the interface and then going into an amp.
- The amp led to the cap which was mic'd up and sent back to the interface to record another track.
- Thus creating the ability to record a guitar, do all the edits on the clean track.
Then in playback the amp would play itself, and you could focus on getting a good guitar tone, then eventually record that tone onto the other track as a final guitar tone.

Does anybody have any idea on how to do this? I assume its rather easy and I would love to play around with things on my interface to get the result. However the risk of breaking something tells me I shouldn't and should just ask professionals for help on the subject.
I am running a PreSonus Firestudio Project interface and using a Line 6 Bogner SpiderValve HD100 head.

Any help, advice or input would be greatly appreciated.

Thanks,

Kyle.

You need a device called a re-amp box. This takes a balanced line-level output from your interface and attenuates and conditions it to produce an unbalanced mid-level signal that can be put into a guitar amplifier. There are active (powered) and passive (unpowered) types to choose from. Many boxes perform transformer isolation to avoid ground loop problems.

Here is an example of such a box, but there are many different ones available from several manufacturers.
