It was all sampled with a Numark TTUSB turntable with the included Numark GT stylus.
Sounds like it too.
No wonder the guy giving them away says
"...it was just a folder of interesting samples I accumulated and set aside for myself while I was working in digitizing my vinyl collection, but after a while it became apparent I wasn’t using them..." It seems like a
useful vinyl effects collection would include period appropriate discs played on period appropriate gear in acknowledgement that all the parameters come together to provide a sonic cue that refers to a specific time and place.
