So my friend is about to send me a complete guitar rig file fully working and what not. But to use my guitar with the computer, I would have to buy something like this http://accessories.musiciansfriend.com/product/SoundTech-USB-Intelligent-Instrument-Cable?sku=332600
Yes, something like that should work. I have one but could never get it to work with Vista. That was a long time ago.
