hey buddy,
Ok, bass drums are tricky, first of all... The quality of mic that you use for the bass drum should be the best one available. If you want the "click" of the hit and then want the bass to follow, position the mic inside the bass drum right in the middle. That way it'll get the initial click of the mallet-strike then the sound will bounce off the front head of the bass drum and hit the mic from behind, remove the spit screen for max click. If you don't want very much "click," Place the mic outside the front of the drum and either loosen the bass drum head facing the drummer, or you can even throw a sleeping bag or pillow inside the drum. Warning though, deadening with a pillow will thump, but it will sound kind of "garage-punkish" and will not provide much reasonance. Secondly, are you recording the drums after the bass guitar track is already done? If so, it's tricky to get a bass drum sound, engineers have been battling this throughout time. The best way to learn is to mess around with it. As far as compression goes, my opinion is that you don't need to use it as much as everyone thinks, keep it light at first and add it as only necessary. Good luck
