Hey Bub! That's always a fun tune to play. I pretty much agree with everything Danny and the others said here about the low end of drums and bass, and the bit about drums being weak in the mix. Mixing in Headphones has never worked for me...
So you have a mono drum track to work with if I read that correctly? I think there are a couple of "stereoizer" plugins out there, and I am in need of one myself as a matter of fact. I think they work on frequency/spectrum analysis and somehow spread the highs toward the sides. Another trick I have been thinking about for this dilemma is to copy the track twice, and with some serious EQing of each end up with a pseudo "kick" track, a "snare" track, and a "hi hat" track, each panned appropriately.
As far as "fixing" your original drum track, I'm wondering if a good 3 or 4-band compressor might be able to boost the output of just a select band of frequency, such as the kick, and then the level of the whole drum track could be raised in your mix. And hey... if none of this works, you could always just "play" another kick drum part in on the fly!! Layers are great!
Depending on the frequencies of your bass guitar and your kick drum, you can sometimes get great separation of the two by boosting a tad in the kick (90k for example), and CUT that frequency in the bass guitar. Boost a bass guitar frequency (say 140k) a tad, and CUT that same frequency in the kick. Then do something similar in the higher frequency attack portion of those 2 instruments so you can define the beater and the string attack sound. The ProChannel in X1/X2 is waaaaay too much fun for doing this! LOL
Unfortunately, I am not in my studio as I listen to your song...on a laptop... and the whole mix sounds a bit mono to me except for the backup singers and oddly, sometimes the bass, are wide. Could be my imagination... been a long day. LOL If this is the case, you may want to think about panning a little differently. Rhythm guitars sound AWESOME when copied to another track, delay the copied track by 10-40 ms or so, and each track panned hard left and the other hard right. (known as the Haas Effect.) It makes them big and wide. Add a different EQ or saturation to one of them... experiment and have fun with it!
Do pay attention to what Danny said about the whole mix being a liitle on the High-pass (bright) side. An EQ adjustment will tame this I think.
A fine first cut Bub! I hope you don't think I've been too critical... after all, it's only my opinion...and we all know about opinions....LOL
I can't wait to hear the 2nd cut!!
