| magnetic pickup?
i once heard a recording made in the london underground using a magnetic pickup instead of a microphone. the guy who made the recording i think built the pickup as well, but, essentially it just grabbed any magnetic fields in the area that were fluxing in the audible range. the sound of the magnetic field around the train engines may as well have been a brian eno synth piece : )
so.. anyone know what kind of device this could have been, and even better how i might get/make one? i wonder if a tape head could be modified..
