easy and fun project man. cut one end off a guitar lead and solder it to a piezo from a small speaker,alrmclock,radio or wherever u find it. And whammo, u got a mic and trigger good to go!
google it for thorough instructions. u will end up making heaps of them like i did and record symphonies of barefeet dragging across carpet and vibrations thru sheets of metal hung in front of gtr amps!
