Yep, I'd like to thank you again for all the info in here. I went from not knowing what I was doing, to recording something that sounds great in my barracks room while stationed overseas.

The basics that I learned here - turn down the gain, add some mids, cut the bass, etc - helped more than I can say. Thanks again!
