my fav technique would be hiting 12" into head just like in this video

Reversing vinly by hand and keeping it going at the right tempo by hand while mixing with the other one! <- thats also very familiar!
another pretty weird and cool thing is makin beat
by just taking the needle and adding on and off the record
and for final tipical low-cut while adding more high or mids is also nice!
