Any pointers on making it less muddy?
Yeah, it's easy, put a High Pass filter on there and kill anything below 40 to 60 Hz. Also, look at the frequencies on the bass, and kick track, and try to carve out (notch cut) places in the kick, and bass where they compete. Also, you can use a ducking compressor on the bass to set it back a bit for the duration of the kick. Put a highpass on everything which is NOT the kick or the bass and cut it at 80Hz or higher to make room for that kick and bass. Bring the kick and bass down the middle and spread and or pan everything else which may compete, i.e., keys, strings.
Then use a MB compressor on the mains, and adjust the lows to taste.
