Assuming that you have an electric guitar, you get a pin that you plug into one end of the guitar cable and you just run it into the mic port. You do the same for an acoustic electric. For an acoustic guitar, i think you'd need a good recording microphone. I dont think any hardware apart from a proper sound card is required. Experts, correct me if i'm wrong.
