Much thanks for the vote, Nonamer. And much thanks for the massive post full of crits and that sweet guide, Monobrow.
Version 4.
I really tried to nail down and attenuate freqs that were muddying up the mix, especially in regards to the main lead and rhythm, which I turned down a bit as well. The tricky part is that I have two lead tracks playing different melodies in some parts of the song, and I never do that. Usually, when I have two leads playing, they're harmonized, so I can get away with sticking them in the same channel and turning the harmonizing lead down a bit. I can't exactly do that here, so I made my main lead dominant around 3 kHz, and the "sub-lead" that I don't use too often dominant around 2 kHz to try and separate them. If anyone has a better suggestion for separating those tracks, I'd love to hear it, because I think it could be better. Spent almost an hour working on it and that's all I could come up with.
That guide really helped me out, especially with the snare.
As always, crits/suggestions welcome.
