Recently I discovered this technique to re-use your old kicks and make them sound nice and fresh. I just used a Sampler some EQ and Distortion. The "magic" happened with the additional use of SerumFX adding another sub bass as well as Reverb and Distortion with heavy use of Serums internal modulation capabilities. Obviously, this is only one way of doing it. There are millions of different eq/distortion as well as SerumFx variations you can use to make hundreds of kicks out of one old Kick Sample.
Enjoy the video and have much fun revising your old kicks!
