FWIW here is my take on your situation.

Since you don't have an amp and your laptop speakers kinds suck I wouldn't use the Rocksmith Cable. I would buy a Roland Micro Cube amp for $150 USD, sometimes they are on sale as a friend got one for $88 USD:

You can either play through the amp as you jam with BiaB or you can use the line out and play and record through your laptop. You could also use a mic and record the amp that way also.

I have a MicroCube and it is one fantastic little amp. In fact it is the only guitar amp I own!

I hope this helps - MarioD


I get most of my exercise these days from shaking my head in disbelief.
