interesting ... you actually created a 'pressure zone microphone' effect
Les Paul's early experiments amplifying guitars used needle/cartridges too
recording / transferring signals with mics sans 'in the air' monitors is really best practice as well
with regards,
Follow Ups:
This is not the same as a pressure zone microphone, which consists of an ordinary microphone located very close to a flat surface. There's nothing touching the flat surface in a pressure zone microphone. Sound waves reflect off the flat surface into the microphone's diaphragm.
I know ... that's why I said 'effect' despite being inaccurate as hell
you're right of course, the LP actually functioned as a diaphragm, the needle as the element ... far more technically accurate, my bad
of course PZM's rely on piezoelectric excitation to work yet his LP was responding to sound pressure and focusing it in [towards?] a narrow gap
anyway, glad that's cleared up thanks!

Hmm, didn't some guy named Edison fool around with an audio recording device that also used a needle?
If art interprets our dreams, the computer executes them in the guise of programs!
I think that was Lenny Bruce
