Electric Prepared Mandolin

I bought a cheap mandolin about 10 years ago for $80.  Then about 5 years ago a mic stand fell on it and cracked right under the bridge (thus it wont stay in tune).  I put it in a closet with intent of smashing it at a show one day.  Instead of destroying it, I put a in contact mic pick up, a 1/4" jack, and "prepared it" in the John Cage piano kinda way by putting paper clicks and wood in the strings.  I play above the neck and below the bridge a lot.  I then run it through my pedals to create odd sounds.  It sounds like the sample below, sometimes.
