This sound is completely artificial. I made it with https://www. Leshylabs. Com/apps/sfmaker/. There, you can make sounds by altering the frequencies and things like that.
Recorded with homemade contact mic set as a stereo pair. This was attached to the zoom h5. I would describe this as experimental, with a finger nail moving between the two contact mics.
Stereo recording of a short scratch bass. Loundge style. I used fruity loops software for this sound. I put an effect of piano roll, an acoustic guitar, an fx scratch, the hip kick for the bass with an other bass effect.
