I'm looking for sample packs where the majority of the kicks peak very very low around 47-50hz. Most of the samples I have peak much higher which sucks, because low kicks sound insane. If you know any really good packs let me know, and also, if you have any good methods for tuning kicks lower without losing quality in the audio, that would be incredibly helpful.

i agree with what marrow said! i just recently started layering sub kicks with more mid-high end kicks and it helps a lot. usually just an 808 will do, but using a synthesizer will give u a lot more control versus trying to tame an unruly sample.

I got some insane samples. I'll send you a few 808's. Shoot me an email at Relative3rdz@gmail.com

try sonic academy kick synth, you can create and edit your own kicks

Also, Kick 2 just released and it's soooo good.

Same for me. Kick2 is an absolute must!
