Ok, I'm gonna go record something now, just something quick, and you can judge it. I was just tried playing through my microphone jack (like, the sound comes through my PC speakers), and it sounded pretty bad. But who knows? Maybe when I listen to the recording, it'll be good quality. Maybe it'll enhance it a bit.
EDIT: I recorded Kick Him when He's Down, and a riff I came up with a while back. And I wasn't really trying, so there are some parts in KHWHD that I deliberately played wrong.
