Will a piece of steel mess mess up the sound? When I put a magnet over the pickup and hit it it makes the weirdest sound. It's sort of like static with a lot of bass in it. I'll have to try it to see if your suggestion makes the same effect. Also you should hear the sound it makes when you switch to the neck pickup while leaving a long magnet/steel metal (I know that it will most likely work either way for this trick) on the bottom pickup. Have it set up where most of it is hanging off the strings, hit the hanging part and it vibrates the strings. It sounds pretty cool.
