I got the plain piezo wafer disks at an industrial supply liquidators, then I solder on lead wires and a jack either 1/8" or 1/4" depending upon the size of the instrument. For those interested, there is a source for flexible piezo film at: http://www.windworld.com in the catalog section I think. Also for a quick and dirty alternative, the Signal Flex SF20 guitar tuner pickup works pretty well as a temporary mount piezo, I've even used rubber bands to hold it in place. The sound in the faux fur piece was picked up off a Peavey amp speaker by the mic in the digital camera, so it is a bit crappy but decent enough considering it is just a low end point and shoot digital. Thanks for having a look. regards BobC http://tinyurl.com/yt8f8j http://tinyurl.com/cr25j http://www.youtube.com/watch?v=YduG4pEej0o http://www.youtube.com/watch?v=xnuChpEHrGc
