As I recall the near zero frequency shift was the first mono to stereo
converter. If you run the down shift to one channel and the up shift
to the other channel and set the shift frequency very low. Very interesting
in headphones, or as my buddy likes to call them "eargoggles".

Frequency shifters were (are) also used for feedback suppression in
sound reinforcement systems (Polyfusion still makes one today).
Shift frequency is like 5 Hz.

Putting a frequncy shifter in the feedback loop of a delay makes it so
each repetition gets shifted again. This sounds very cool on percussion

Just mining the garbage dump in my head.
