lol i do know what triggers are...i am a drummer...duh..and maybe you didnt see, there were mics on those kicks..not triggers...when you tune the batter head of the bass drums down, you get the ultra slappy sound, and when you use a wooden beater, or impact pad...it makes that slap stronger...duh there you go triggered sounding drums without triggers...i hate when people try to shut you down...but then its so fun turning it around on
ps....this method only works if you have mics, otherwise its a very shallow sound...duh again
