Hey, all. Thanks for your replies. I'm a noob with all of this talk of gear and cables and whatnot (I had to Google DAW to see what it meant).

I'm looking for the simplest solution. I have an amp, but it's this tiny Marshall device that takes a nine volt battery and is small enough to clip on one's belt (it even has a clip). If I ever get good enough to play with other people, I'll need to a get a better/real amp. It doesn't have a line out, just an input and a headphone jack. You can see it here: http://amzn.to/1BNTjWX The Micro Cube amp that was suggested looks pretty hot (or maybe it's just the guitarist).

Still, I know my way around a computer pretty well. How hard would it be for me to set up all the drivers and whatnot for the Rocksmith cable? I'm not sure if I would even know if it was working, etc. Are there videos online on how to set up a cable? Should I download amplitube and try that?
