I boost 60hz (when the sample or the real kick-track has not enough low end) I use the 90-120hz area for the low-end of the bass guitar.
You can also boost 1khz/1,5khz/5khz and for extreme metal-clicky kicks 10khz
I usualy cut out 300hz/500hz/or 800hz
But it all depends on the source. I would never boost the low-end on a ssd kick nor would I boost the highs (for the klick) on the andy sneap kick-gog
