I've been trying to get this sound for a while now. I use an Ampeg SVT4PRO head and an Ampeg PR410HLF cabinet and the sound i want is the low-end "clicky" sound (like KoRn, Coal Chamber...etc) just to name a few. How can I get that sound? I have my mids off and my 150 Hz on my EQ turned all the way down. Do I need an effect or is there some special way to set my EQ so I wont have to buy an effect?
