What is Re-Amping?

Ever heard of re-amping?  It's a neat little trick you can do with audio you have already recorded, especially electric guitar - though the concept is valid for anything.  The idea is that instead of recording your electric guitar by mic-ing the amplifier, which is the usual way to do it, you record a non-amplfied version of the guitar part.  Then after it is recorded, you route that guitar part back out of the recorder (or recording software) and plug it inot the amplifier.  Just hit "play" and the guitar part plays back through the amplifier, which you can record onto a different track.
This allows you to try out different settings and sounds on the amplifier.
