Well, a good pointer is to balance opposites.
Kick should balance the Hats.
If you go down low with the bass, then you need some fizz at the top end to balance out.
Work your way in to the mid frequencies.
Generally a good guide to building a solid groove.
Is to get the kick and the hats to sit right.
THEN gor for a sound that hits the very mid frequency right inbetween the kick and the hats. If you get this balance right, then anything you then fit inbetween these 3 key points will work into the already nicely balanced groove.
Then you can either work in the bass slightly above, or slightly below the kick.
Or when you get really clever, you can plonk the kick right inside the bass.
But this is another matter.
