thanks, sounds interesting, i'd love to give this a try.  however...

what's a 0 volt wire?

this is a very simple pair of self-built contact mics, which i wired to 
the xlr connectors based on some recommendations from rob at aquarian 
audio.  the ceramic and outer rings of the piezos are wired to pins 1 & 
2 resectively, and pin 3 is wired to a foil shield which surrounds the 
piezo.  then the whole shebang is plasti-dipped.  does something in 
there equate to a 0 volt wire?

and for the record, the recorder is a fostex, fr2-le, super-modded by 
oade bros.  it *only* happens with these self-built mics, though, so i 
strongly suspect the problem is mine and not the recorders.  i am no expert.

best,
patrick
