Reverb with predelay, huge amounts of compression, then layer about four or five different kicks on top of each other - each one adding something different.
Then you get an uber kick with a beefy chunk and gut kicking slam.
ok so i have it going 1 2 3 4 (the kicks lets jsut say) and set the predelay to wear it like it...then add compression (to make it thump right)... and do the rest of the layed kicks get the same predelay and the same compression or jsut predelay or jsut compression etc....and after that is all said and done i get another kick to be the main kick on top of that? its sorta what i do now..but i guess i havent found the right combo yet i eithe rover do it or under do it....thanks man great advice..gonan go try now
