What's your favorite instrument that really gets through to you?

Electric guitar, preferably with heavy distortion. Louder := better.

No but seriously I love heavy music so much. It's fun to listen to, fun to play, and it's just had a positive impact on my life. If you want to really tug on my blackened heartstrings, you gotta do it through distortion, preferably an HM-2, in as low a tuning as your guitar can handle.
