Here's all the samples I used to perform the Scratching Solo in the "Knuckle Duster" film clip...plus a little more...

Kit contains 12 samples (4x classic tears + 8 vocal samples) ready to be loaded into your samplers.
For my SP-404 fam, the .wav files are numbered corresponding to which pads I used in my layout.
