Sounds good man you have a good base tone not too much gain, no harsh frequencies. Did you double or quad track this? I always quad track my guitars to get that big fat wall of sound I think that would be a huge benefit to your tracks.

yes I only double right now. I'm not sure I know how to low shelf/high shelf a guitar, which is how I think you're supposed to do it when you have that many tracks.
