Re: transducers (piezo buzzer)

2002-11-05 by Mike Marsh

I didn't get home 'till late last night so I couldn't try.  Tonight,
though, I promise...

The piezo acts like a pick-up when attached to the bridge of a guitar.
 The mod is simply soldering a cable to it with a jack.  Sometimes I
cut the it into a different shape (it's normally) or just to get it
less hot.  The output is amazingly loud.

The idea, I guess, is instead of having it translate vibration into
electrons (as it does when it's a pick-up), but to translate electrons
(from the MOTM) into vibration that will move the top of the guitar
through the bridge.  Then mic the top to record.
