Hook the headphones out (or Line out) from your amp into the MIC jack in the back of your puter...you'll need a 1/4" to 1/8" adapter. when you do this make sure the mic gain is turned all the way down (DOUBLE-CLICK the speaker on your task bar to bring up the volume controls for your inputs). Have your amp turned up to a reasonable volume and slowly bring the mic volume up until you here it good and it doesn't distort.....At this point, all you need to do is use a software program to record what you want as a wave file.....I could go alot farther into explaining this, but I think you get the jist and I hate typing long rsponses :).....V :D
