Ghost Kicks

[sYgMa]

Depending on the effect you want you could also cut a little of the attack (to have a smoother sound)

and also, ghosts sound better with simple drum patterns than complex ones...

i agree with the "feel" more than "hear" point about ghost kicks. I filter my ghost kicks so you get a muffled mid-low feel bump before the main kick hits. takin away the high frequencies gives it a smoother position in the mix of things.. in my opinion.
